    Chrysler 75 horsepower seems to lack a lot of power at wot

    The motor ran great last season, and the beginning of this season. I noticed every once in a while when I hit the throttle, it would seem to cut out, and not want to go occasionally like halfway through the season. The loss of power though was very sudden. Like literally the last time I brought...

    Chrysler 75 horsepower seems to lack a lot of power at wot

    Okay, so I did a leak down test on it, and when I put cylinder 1 at bottom dead center, and I can hear air coming out of all 3 carburetors. I pulled one of the reed valves out, and I tried flipping the plates around on the body of the valve, and it made the gaps bigger. What should I do about...

    Okay, so there’s 2 places the exhaust would exit? Because there’s the exhaust holes that come out the back of the whole outboard assembly just below the power head. But they also have exhaust go through the bottom right by the prop as well?

I hooked up that hose that runs from the intake where the reed plates bolt up to, to the air horn, and I...

    Chrysler 75 horsepower seems to lack a lot of power at wot

    At wot the boat seems to lack power and it also seems to ping a little bit too. I just rebuilt the carburetors this spring. It seems when setting the idle, even with the idle speed screw on the timing tower not touching the block, and pushing it in, the side of the rod hits the block, it still...

    Cranks but no start

    I cleaned out the carburetors two months ago, it gets fuel up to all three carburetors, has spark, and gets 120 psi of compression all across the board. The timing marks line up with the timing tab and the t on the distributer lines up with the flywheel, and the #1 cylinder is at tdc. I took a...

    Will a four stroke tach work on a two stroke?

    So I have this automotive tachometer that I want to install on my boat, and on the back, there is a switch where you can either hook it up to a four, six, or eight cylinder engine. You hook it up to the ignition coil I believe, and I was wondering if you just switch it to the six cylinder...
