Evinrude 9.9 -15 hp

[KonaB206]

I posted another post about a motor I recently picked up for sale that was seized up and I also wasn't sure what kind of motor it was

Here's a few updates I have so far on it

I noticed at first the powerhead was white on it but some of it was peeling off and it was the blue metallic paint underneath so I'm thinking it could possibly be the original powerhead but this motor is an evinrude and not a Johnson. So that made me feel a little better about purchasing it.
still cant find any identification as to whether it is a 9.9 or a 15hp tho.

i soaked pb blaster in the cylinders for a few days and it broke free and it is no longer siezed up. On the third day I lighty tapped with a flat head back and forth opposite directions on the flywheel teeth and it came free!

I also refilled fresh pb blaster in the cylinders and gently moved the flywheel around here and there for the next few days when I had a chance .

Went today to check the compression and I'm getting 90psi
On the upper cylinder and 110psi on the lower cylinder
in yalls opinion do yall think that's good enough to go ahead with the normal repairs to get it up and running.
and will the psi likely go up a little on the 1 cylinder a little maybe.

You can see the difference by looking into the carb with the choke open.. The 9.9 carb tapers down and the 15 does not...

go or no go opinions differ


I would try to save it … saved worse my $50 kicker on my Misty River took over a week to free up with a peg and hammer

runs real good now

Nice looking boat!
I want to go for it and try to get it up and run ing for as little as possible.
what kind of readings did you get on yours after you got it freed up

If it now spins free and smooth with no bearing rumble (plugs out), keep going. Once running, give it a decarb w/seafoam and see if comp psi increases in the low cylinder. Even if it doesn’t, you’ll likely have a great runner. If there is bearing rumble, bring oars

How do you tell if you have bearing rumble?
what does it sounds like?
