Going to replace the fuel lines on the Bearcat I picked up last spring (2011)
Going to check it out and rig it up to my pontoon. Right now there is a 62 Homelite on it. It needs some TLC so I hope to run the Bearcat this summer as long as it runs as good as it looks.
For standby boat I will run my 1960 Larson All-American with a 59 Fat Fifty. B)

That's progress! :lol:
I have one torndown, replacing valve guide seals, piston rings. The block was white and I had a blue crankcase and other blue parts. I'm replacing everything with white parts.

Saturday more progress, the block is honed with a nice crosshatch then scrubbed in hot soapy water and rinsed. Cylinders were coated with light oil. I put a new ring in and checked the gap, .022". Mic'd the bore for taper and size, it's perfect. Chipped loose paint off the block, wire brushed and put a base coat on. Today I'll replace the seals, I had previously checked the valves for leakage, they are perfect. I don't think this block has many hrs on it.

Dave, I'm trying to motivate you, did you change the fuel lines yet? ;)

Yes, Dick you motivated me. I took off the old fuel lines yesterday. Went to the auto parts store and picked up some new fuel line. Just received my fuel pump gaskets from Bill too!
Got to get the fuel pump mounted and fuel lines and test her out.
Pulled the O'le 1960 Larson out powered by a 59 Fat Fifty.

Alright Dave! Can't wait to hear how it runs. It looks in such nice shape that it should run like new.

I just finished up installing pistons, taking a break now. Maybe the bottom end later today.

Yep Dave it's getting that time of year. While I do have four others to chose from to run this year, I would like to get this one finished and run it.

Had to pull the port waterjacket cover, the block drain hole was stripped out. This is the second one like this that I've welded up the hole, ground off flush then redrilled and tapped. Got rid of the two studs for the rectifier since one of them was broke off anyway and then welded on a single stud for the Radio Shack rectifier.

One of these days I'm going to have to get a bottle of argon and try out that Lincoln Squarewave Tig welder I bought in January! I've got lots of little projects for it.

Today I took the Bearcat fuel pump off the Homelite. Last summer I robbed it off my 70 Bearcat and put it on my 62 Homelite.
I was getting fuel in the oil. I'm thinking it was something else that caused that besides a faulty fuel pump.
I'm reattaching the original fuel pump back on the Bearcat. Check it out and go from there. I do have a standby electric pump.
Keep you posted. Still waiting on my pontoon trailer to get the pontoon moved to take off the Homelite. Will store it in the barn. The Bearcat is in the garage. Going to use the Old style rigging.

Got the fuel lines replaced Battery cables hooked up.
After a lttle coaxing, it fired up Blue smoke everywhere.
That cleared off after the excess oil burned out of the cylinders from laying around.
But..... Not pumping. It is a 70 model with thermostat. No water comming out pee hole. I'm wondering if the leg is deep enough in the water. Right now the water is about 3" above the anti- ventalation plate.
I have a new impeller I guess I should use on it with these symptoms

Update on Bearcat.
About a week ago had small mishap. Motor stand failed. Bearcat landed on it's head. Smashed distributor was the only damage. Lucky I had a spare dist.Had minor surgery last week. That set me back. I'm able to get around a little better now. So I installed the spare Dist. Fired right up.
Put the leg in a deeper barrel. Seems to be pumping water at high idle. I have two Tell tails one on each side of the motor. Water is only coming out the starboard side tell tail
It is a 1970. Does anybody have this type of cooling system? It has the thermostat.

I guess I got to pull the lower and check the impeller. I have a new one here from Bill R.
All sugestions appreceated

Dave,
I have 2 "F" models like yours, neither has "two" tell tales. The only tell tale you should have is the one on the stbd side under the carbs. My guess is the one you see on the portside is the block drain and this needs plugged off. The water from the pump enters on the portside of the block at the top and circulates downward where it then crosses to the stbd side and forced up to the top of the block and into the manifold. If this portside telltale is open there is not enough pressure from the pump to push it through the stbd side until you rev it up. Plug it then see if the port tell tale pees at idle.

Thanks a lot Dick. That hose on the port side did not have a cap or plug on it. The past owner must of winterized it and left the cap off.
When I reved up the motor water would come out the tell tail on the starboard side. Slow idle no water coming out.
I will plug it and let everybody know .
Thanks again,
Dave

Re:Working on Bearcat for the pontoon 6 years 1 week ago #61135

I have what looks like 2 tell tales on my homelite but the one on the port side a breather tube for to motor. check and see if the one on that side is coming out right were you add oil and fallow it down and see if that is the hose on that side.

Here is a photo of where the winterizing drain is. It is a bluish color on the motor on the motor pan near the transomom clamps.
blow up this photo you will see it.
The hose that hooks on there comes from the water jacket on the port side.

And this is the one I'm assuming was also peeing water while you were running the engine?

Nope. It was plugged up with mud dobber junk. so I cleaned it out. I think I'll have to pull the lower to see the whole picture.
Dick what kind of cap did they use for this port side drain for the "F" motor?
Was it some sort of snap on cap?
Dave

By the way your newest motor sounds great.
Mine starts and runs great. Just not pumping right

Dave, yes I've also experienced the tell tale plugging up, I've got a wire in the boat that I'll run up the hose to clear it. A couple of my engines were pretty rusty in the water jackets and I'm sure some of this crud broke loose and restricted flow. after a awhile it cleared and has been fine. The powerhead I just replaced was like this.

Dick,
Yes that is what thought. The snap on cap is missing to my winterizing drain. I guess I will just fix up a thing to plug it until fall winterizing time to drain the block.
Thanks so much for filling in the blanks for me on this motor.
Next step will be checking water pump impeller after I get healed up more. I have a fresh impeller instock.

Are these lower units with two water tubes harder to line back up than the old style one water tube system?
I've pulled my Old Homelite lower several times.
Dave

Ps. My Tell tail line is open.

Dave,
I've put a petcock in mine for draining the block.

No worries your engine has just one water tube coming out of the waterpump. I have one here, a '65 with the 2 lines and yes they are a bit of pain to line up!

I got more water flowiing after plugging the winterizing drain hose at idle.
How hot should the water be coming out my 1970 Bearcat tell tail? It seems quite warm. But won't scald you when you let it run over yor fingers.

Help somebody

Not sure as to the degree temp but my Homelite it is almost to hot to put you hand in tell tail water.

Dave,
Funny you should ask this question as I have been monitoring the temps on mine with the infrared thermometer. At the tell tale I'm showing 116 degrees. I'm running this on garden hose. If you are running in a barrel keep in mind the longer you run the hotter it will get as you are also heating the water in the barrel.

Mike, is your tell tale coming from the top of the water jacket on the stbd side? This is where my '65 Homelite is hooked up and at idle (600 rpm) it just blows steam, bring it up to 800 rpm and it's a steady stream of water. Manual says it's normal and I ran it one season with no problems.

Dick,
You are right about barrel water running hotter.
In the manual I have for these motors with thermostats ,they say tell tail water temp is around 120 deg.
My Bearcat will steam a little at low idle than come OK when I rev up the Rs.
Since I'm pumping water fairly well I think I won't pull the lower. I have a back up pontoon if I have to work on the bearcat powered pontoon. Now that I got my own trailer it won't be a problem

Photo is my 62 Homlite

Re:Working on Bearcat for the pontoon 6 years 1 week ago #61351

My tell tail is coming from the top of the motor and it never steams. I"m iddlling at about 450 rpm and on start up only takes about 45 seconds for it to start pumping water out.
These motor are still new to me. I got to get a good tach and oil gauge for mine.

Dave,
My experience with the three late engines I have with the tell tale coming out of the manifold below the bottom carb, all of them pump a steady stream of water at idle. If it were mine I'd pull the lower and check the impeller for piece of mind. Just my $.02

Re:Working on Bearcat for the pontoon 6 years 1 week ago #61431

I'm glad the subject came up. After all the wait, I'm finally putting my outboard back together. One question. I can't make heads or tails of which way the seals go, just above the needle bearing below the impellor housing. It looks like the spring side faces up. The pressure side is always the spring side. When pressure pushes the spring, it closes against the shaft. At a closer look, it looks like the face side faces up. ??? It also looks like the flat end of the needle bearing faces up. By the way, I've finally found a muffler shop that has aluminized steel. I've made a new muffler. I'll post pictures later. I have to drill holes in it, still.

The spring side faces up, there is more pressure on the the water pump side than the gear case side.

Thanks. I kinda thought that, but, wasn't sure. I'll post photos of the re-assembly. After it's all assembled, I'm going to start the trailer. That's going to be fun. I'm changing the design of the color scheme just a little on the outboard.

Back home now. Friday I'm pulling the lower unit to inspect the water pump impeller. The Bearcat is running fine right now. Starts right up at just a touch of the key. Just not pumping water like it should.
Will keep you guys updated. B)

Well, I pulled the lower unit today.
Low and behold! Semi fried pump impeller.
The pump housing and stuff looked good.
Pulled the old impeller off and replaced it with one of Bill Rs .
Everything is back together. Just got to test her out to make sure she pumps water.
From the looks of the old impeller, she was run dry. sindged the vanes plus the vanes had a bad set to them.
If it pumps fine she will be replacing the 62 Homelite on my pontoon.

4 Stroke: It wasn't too hard to re-alighn (sp) the driveshaft with a help from a friend.
Wish me luck .

Dave,
That's a really nice cabin and what a view!

Sounds like you've solved your pump problem, you should get a good stream out of it now at idle. I was given a '72 6hp Johnson on Friday, Saturday I had it up on running however it's not pumping water. I checked the impeller and it looked okay. Long story short it would pump at idle but not above, too much set in the impeller. Great running little kicker but man it would have cost a fortune to have a shop fix all the little things wrong with it!

Sometimes I can align that driveshaft no problem other times I got to have my tongue in the right place and mumble the right curse word! :angry:

I'm ready for sea trials and fishing trip in the morning.

I wish ya good luck but I don't think you'll need it!!!!
