Well, since I don't have the $$, I have decided to pull the power head and take a look inside. What the h#ll, I've got nothing to lose and maybe a lot to gain.

Went to the marina tonight and started removing all the cables and hoses hanging from the engine. Took digital pics and notes so that I can get it back together again. If the lousy weather we have been having in Boston clears for the weekend i may have it off soon. I'll let you know what I find.

Repirts,
Good Luck!! Let us know what you find. Probably not a good sign when hear metal on metal. When did you buy the boat? Can you contact the person or place that sold you the boat and ask them for assistance helping you fix or locate a new powerhead?

Bought the boat 1st week in June. Got it for about what the hull and trailer are worth. Maybe a little high but in the right ball park. Sold "as is" so I don't think I'll get much help from seller.

Yah, metal on metal doesn't sound good! But, let's wait and see.

My son and I pulled the powerhead yesterday. What a job! There were ten studs with nuts holding the powerhead on. Nine let go pretty easily but the tenth was another story. We were using a boom truck to pick up the head. That one stud was stuck firmly enough to lift the boat off the trailer. Eventually, with enough pounding and prying we got it moving a little. All of a sudden it let go and there was enough tension and stretch in the line to catapult it about 12 feet into the air. Luckily the lift line held and it didn't hit anything or anyone. When it let go both my son, Christian, and I hit the dirt. I can't remember jumping that far or that fast in a long time. Found myself under another boat about 10 feet away.

Right now it's outside letting some of the gas fumes evaporate before I bring it into the cellar. I'll start on it tonight. Hope when I open it up it doesn't look too bad.

I've pulled the cylinder heads and the exhaust manifold. So far it doesn't look too bad. One cylinder has a small score that is just detectable if you run your fingernail over it and one head has the nicks mentioned before. Pistons and rings look good. Everything seems OK when I turn it over with the flywheel. Before I pulled the power head, I checked the compression it was between 120 and 125 all six cylinders.

Now I'll flip it over and open the crankcase to take a look.

Good Work!!

This engine has chrome bores and can't be honed. The only way to do anything with the cylinders is to have it bored and sleeved. I only want to get one or two more years out of it. As I said, it has one very small score in one cylinder, should I have it sleeved or should I forget about it, close it up and run it..

I don't know any better, but you might post the question on bostsetup.com or iboats.com. I've gotten some excellent information/help from both sites.

If comp checked out at 125 PSI and that is within specs I would not do anything as long as bottom end bearings look good.
You can do a leak down test, I have never done one on a two stroke but have done many on car engines. This is the real test of the sealing of the rings. Not sure what % of leak down is OK for 2 stroke.
