I bought a stratos boat with a 1995 Johnson 130hp. It ran great at first then began cutting out especially at WOT. I replaced the plugs, cleaned the tank and put in fresh gas, new fuel line, new oil and oil line, cleaned the carbs, cleaned thermostats and installed a new water pump. It ran great after that but last night at the lake running WOT it just died. I tried cranking it again and it acted like the battery was low. After it sat for about 30 min with the cover off it cranked right up but wouldn't get above 1500rpm. It was vibrating heavily and acted as though one cylinder was dead. Help please???

Re: 1995 Johnson 130

I am sorry to say, but it sounds like you have serious problems.
The dying at WOT, and then immediately upon trying to restart, and it acts like a dead battery...classic symptoms of an engine that has overheated and a piston has "swelled" in the cylinder, causing excessive friction, shutting down the motor, and not allowing the engine to turn over freely on a re-start attempt.
When the engine cools, the piston returns to normal size, and the engine can turn over.
You should immediately do a compression test. I fear that you will find at least one cylinder low. The cause is lean running on the affected cylinder.

Had it happen to me....

That is exactly what happened. I found one cylinder with low compression, I believe you are right. What can be done about this problem? What is the cost to fix that cylinder and how can I prevent it from happening in the future?

Post the compression numbers please.
The very next thing I would do is pull the cylinder head off the bad bank.
Examine the damage...
The powerhead likely needs to be rebuilt. There are many ways to go...do it yourself, get an exchange p-head and put it on yourself, let an Evinrude shop do it,
etc.

The probable damage is a scored cylinder and piston skirt/rings. The p-head must be torn down, and the damaged hole bored, new piston, rings, and re-assembly. You can repair only one hole if you want, you don't have to do all four. Doing all four is recommended though.

I have a V6, and it runs about 1000.00 for parts and miscellaneous junk to complete the rebuild. That is doing it myself.

Rebuilt exchange p-heads vary in price, probably 1700 to 2400 depending on who you get it from.

I won't even suggest taking it to a shop...$$$$$$$$$$$.

BUT!!! You must find the cause of the lean condition that caused the damage. Possible clogged HS jet in the carb that feeds that cylinder.
If you don't find the cause with a thorough autopsy, you will likely damage any repair that you attempt.

Where are you located? I could help you if you are in Florida.
