    Water Temperature Gauge Extreme Fluctuation with Throttle

    Hey, guys and gals... I've got a boat with a 1994 Evinrude 175HP V6, and as far as I know it has the original water temp gauge. The question I have is on the behavior of the gauge. It reads basically zero at idle (maybe barely off the lower peg), but moves with the throttle...meaning that at...

    Where does this hose go?

    In the picture below, in the upper-righthand corner, there's a tube marked #30, with a tee. I'm putting this engine back together, and I can't figure out where this goes. It's a short tube, about two inches long, and seems to point off into space. The tee is not a check-valve - it's just a...

    Why does the OEM manual say this?

    Help! Motor mount bolt pushed into water passage - what to do?

    So, I was in the process of torquing down the retainer bolt for the upper mount on my 175hp Evinrude V6, and although the manual says torque to 100ft-lbs, after quite a bit of cranking, although the bolt was getting tighter, something just didn't seem right. I stopped around 60ft-lbs to take a...

    Need help getting started - No oil seized two pistons on Evinrude 175 V6 two-stroke

    Re: Need help getting started - No oil seized two pistons on Evinrude 175 V6 two-stro These came out of the hole in the block under one of the main bearings. At least the washer with legs did. The flat solid disc, I'm not 100% sure about, since I found it when taking the crankshaft apart...

    Need help getting started - No oil seized two pistons on Evinrude 175 V6 two-stroke

    Re: Need help getting started - No oil seized two pistons on Evinrude 175 V6 two-stro A couple more good ones: Rod caps from piston #3 (the worst one) This is where the steering arm connects. Severely rusted. Is this a problem that should be address - or "normal"?

    Re: Need help getting started - No oil seized two pistons on Evinrude 175 V6 two-stro As requested, here's some pictures that may help - I'd be happy to take any more if specific shots would help. Here's the crankshaft where the rods 1 & 3 connect: It's easy to tell which ones took the hit...

    Need help getting started - No oil seized two pistons on Evinrude 175 V6 two-stroke

    I am in a bit of a pickle. I just got a 1994 Evinrude V6 175HP two-stroke, and it was running fine until someone added gas, but no oil...:eek: Predictably, the motor seized, and now I need a little help getting it repaired. I have a fair amount of mechanical experience - mostly on cars, but...

    1973 Johnson 65 hp loss of power/weak in the water

    I have a 1973 Johnson 65 hp that I've been trying to get running right, and I'm not sure what the issue is. I thought I'd post on here to see if anyone has any input, but also, I thought it would be good to provide a thread where I can post the updates and results. I replaced the main gas...
