Re: electrique probleme

Most likely is the rectifier. Refer to your manual to find it and test it. If indeed bad, don't run your engine until it's replaced or bad things can happen

Re: electrique probleme

Sly....we gotta keep your posts' together here ol' buddy. Hard to keep track if we don't.<br /><br />Let me ask a couple questions. When you throttle forward, in the water, does the engine rpms go high but you don't go no where? Or do the engine rpms go up a little and that's all?

Re: electrique probleme

Re: electrique probleme

OK sly....your problem may not be in the lower unit. If you have trouble getting rpm with the throttle and have to play with it to get it to go, then it may be a carb problem. Maybe some junk in the float bowl. Have you check the fuel lines to make sure they are all tight and secure? Primer bulb is good and fuel tank vented? Choke is coming open? Here's something to try.....<br /><br />Put some pre mix fuel in a squirt bottle. Have a friend with you. Put the boat on the water. When the throttle is forward and not getting any rpm, squirt some premix into the carb and see if the rpms pick up. If they do, probably a gas feed problem. <br /><br />Also make sure the primer bulb pumps up snug before starting cold.<br /><br />One more thing to try.....look on the front of the fuel pump. The big black cover on it. Remove it and check the fine mesh screen behind it. Remove the hose that goes to the carbs and temporarily attach a hose to the fitting. Have someone crank the engine. You should have fuel squirting out the hose pretty good.<br /><br />Keep us post sly.....

Re: electrique probleme

Well sly....that's what we are trying to find out. Possible yes the lower unit may have a bug in it. But let's get this other stuff out of the road just to be sure it is the lower unit.

Re: electrique probleme

i find that here in iboat if posible its the probleme for me because i change everithing inside the lower unit maybe i do error but im not sure what i told in this post were i see this triangle??? (((Look behind the prop at the bearing carrier. There should be a triangular cut-out on one side of the bearing carrier. That cut-out has to be at the top for exhaust gases to pass through it. See if maybe someone put it in wrong.))
