    66 Big Twin won't throttle up, Carb Issue I believe

    So this summer I picked up an Evinrude 66 Big twin model 40652B. After rebuilding the carb and replacing the fuel pump I got it running. I can start it, it idles fine, and can drive around at low speeds no issue. However, when I try to get on plane it starts to rev, then the rpms come back...

    66 Big Twin starter bracket bolts?

    So I picked up a 66 40hp big twin model 40652b, and I'm working on getting it running. Upon getting it to idle briefly, I noticed gases coming from the holes in the starter bracket, and to me it sure looks like there should be some bolts or screws in there. I'm having trouble figuring out...

    470 vapor locking I believe need help correcting, Yes I've searched

    Trailer swap question, can the boat be too small for the trailer?

    So I picked up a boat for the motor to replace the blown motor in my Century. I pulled everything off, dumped the boat, and now I have the trailer. The trailer under my fishing boat is too small, and I had been wanting to upgrade it anyway, so now I'm thinking, why not use this bigger trailer...

    470 motor mount inspection?

    I'm installing a used 470 in my boat to replace the one that blew up. Obviously if I need to replace the rubber motor mounts, now is the time to do it. My question is, is there a good way to inspect/ test them? I've tried searching, and did find the info I was looking for. Visually they look...

    470 Clean up cam shafts prior to speedi sleeves?

    OK so I picked up a donor boat for the motor, and after I got it running, I found it was leaking coolant out the weep hole. I tore everything down today, with no issues, and you can see how bad the second seal is. But my cam looks pretty beat up, so I was wondering about what the best way to...

    470 fires when starter engaged, shuts down when ignition is in the run position

    I blew my 85 170MR and picked up an 83 470 to replace it. Trying to get it running, but it only fires while the ignition is in the start position, and cuts out in the run position. I was told this was the condition it was in when I bought it, but it wasn't even doing that for a while, someone...

    470 wiring harness compatibility.

    So I blew by 85 170MR which we all know is a 470. I picked up a 83 viking deck boat with a 470 in it for $150 and I'm trying to get it running, to make sure everything is good to go prior to installing it into my boat. Who ever had worked on this thing in the past should be arrested. The...

    Buying 470 with seawater piped to engine?

    This is what happened to mine. I think'll I'll hold off on it for now, I have another option that might pan out. I don't want to spend too much time tearing down and rebuilding in the summer.

    Buying 470 with seawater piped to engine?

    So I'm looking at buying a boat for the engine, the Mercruiser 470, which as you know has the fresh water cooling system. Well I guess the heat exchanger was bad, and instead of spending all the money to replace it, he re routed the seawater through the engine. My question is, would that cause...
