I have an '86 Mariner 115 powerhead that I would like to rebuild myself possibly. The motor seems to run well but compression varies from about 120 to about 140. It also seems to have a tick at idle. The motor looks like it has been opened up before (new gaskets). I'd like to go through it...
I have a '80 Glastron GT-150. The boat is in excellent shape but is slightly oxidized on the top portion. I want to try to buff it to get it as close to the original shine as possible but I have never done this before. Should I buy an orbital buffer or one that spins in the same direction...
This happened a couple weeks ago. There was a middle aged gentleman and his wife picking up his new boat at the marina where I stopped for gas to fill mine. He got the trailer hooked up with the lights and chains and everything and gently pulled out into the road then all of a sudden a huge...
OK, I've gotten mixed responses on this question. Some say 82, others 84, and others 85.
I'm mostly concerned about the information with the Mercury I6 motors. I had a powerhead go bad on my '86 115. I swapped an '81 115 powerhead on it which runs great but doesnt have the power of the old...
I had the powerhead go bad in my '86 115 so I switched to a good '81 115 powerhead. It runs great but doesnt have the power of the old powerhead. I was told that sometime after about '82 the motors were rated at the prop instead of the crank. Is there an actual difference between these two...
What is the difference between an I6 powerhead that is a 90 and one that is a 115?
I had a powerhead go bad on an '86 115 and I swapped over a good powerhead from an '81 motor but it feels like it is a 90 HP powerhead since it doenst have the power of the old one although it is running great.
I'm starting to become an expert on this I6 Merc's.... I have/had an '86 Mercury inline 6cyl that had great compression but the trigger coil went bad so I changed that and the stator when I was in there. I was out for a whole day in the boat and went through a tank full of gas and the thing...
'78 Johnson 150 V6 No spark on the entire port side. I switched the power packs around. (Figuring it was that) Still no spark on the port side. Where do I look next?
I have a 1978 Johnson 150. The carbs were just rebuilt. New spark plugs. Great compression. The motor is hard to start when cold. I prime the bulb and when you hit the key it turns over and then starts to fire but the starter immediately disengages and it stops. You play this game for a few...
I've got a 78 Johnson 150. The engine is all original and was never apart. The compression is 110 on all cyls. When I bought the motor it was sitting a while. The thing ran horrible when I got it on my boat. I then took it to a marina and they put new thermostats in it and adjusted the...
