Just thought I would post up my recent findings. I have a OMC 3.0 L that I recently discovered has a decent crack along the block underneath the manifold. It ran fine with no water hooked up then when I had done all the work I needed to, to the boat and engine I hooked up some muffs and started...
The video below is what happens when it does actually somewhat "start". But this is only with the starter still engaged the minute I try and put it back to on position at the key it shuts off. Any Ideas?

So I recently purchased a boat with a 1987 (I Think) OMC 3.0 4cyl Serial number T0969422. When I turn the key all I hear is a Click noise and then nothing happens. I replaced the solenoid because that is what the marine store recommended. Any other thoughts? Would it not start if the outdrive is...
I have a 1987 Cuddy Cabin that i just purchased , where you go into the cabin part of the boat in that step down there is a hole that i assume is suppose to drain water that collects there but i can see the water just sitting beneath the whole , my question is how can i get the water to the back...
Hi all, I just bought a 1987 18' Sport-Craft Cuddy Cabin for $500. I have a few questions, the hr reading on the dash is 424.3 is that a lot of hours on a mercruiser engine, also I did not get the opp to test the engine because no battery, and its been sitting a while and I didnt want crappy...
Ok I am trouble shooting my 1975 Mercury Outboard 85hp. I Am now going on my THIRD switchbox on this motor. So I read it might be the trigger. Does the trigger transfer power through the switchbox to the coil ? Also I am not positive on the whole jumper wire tests. ANY INFO would be greatly...

Alright recently I just purchased a tri hull boat with this motor on it. It will run fine on high idle but I can not get it to run without being on high idle which is bad because when I engage it into forward it jerks and for a 50 hp it is not going as fast as it should and most of the time it...
