    Motor still idles rough

    Took the boat out again - seems to be doing better and it isn't cutting out. It is also easier to start. just touch the key fires right up. Everything way better than it was. So I am gonna leave it alone for now. Time to go fishin.

    Hate to say. its still running rough after all that. One thing i noticed it runs better with muffs than in water. Back pressure problem? I did change reed valves a while back. It was spitting gas out the carb. other than that i am lost. I have had this boat and motor 21 years with little...

    running rough at idle

    Hate to say - but motor still not running right -all that work for naught. One thing i have noticed is it runs good on land but when i put in water acts bad. Back pressure problem maybe. i changed the reeds a few years ago.

    what is the torque for those 15 screws on cover plate. I have a book it says 100 inch pounds. Another source says 270 in pounds. also torque for adapter plate to motor. Book says 225 inch pounds. Sounds kinda low. But this is aluminum.

    Razor blades just wouldnt cut it. So i bought an air powered angle grinder and some of those round scotch bright pads. that did it. You have to hold grinder perpendicular to work and keep it moving. Dont apply any pressure , let it do the work. Saw a you tube video, thought i would try it.

    running rough at idle

    well looks like you are right- penetrating fluid nor heats works- gonna have to drill it- No way to put on drill press so will have to do by hand- also figured this plate can or will be sacrificed. as long as i don't screw up the block. Have to buy corded drill. My cordless useless for stuff...

    running rough at idle

    ok update- the break down says there are 15 bolts I count 16. These bolts should go all the way thru the intermediate plate and screw into the block. For some reason I have 2 bolts one on top and a second directly below it that have a 1 inch 1/4 20 bolt screwed into intermediate cover why...

    running rough at idle

    I attempted to pull port cover plate off. Three of the bottom bolts broke. I was very careful but didnt matter and of coarse they broke off 1 !/2 to 2 inches down where I cant get to them. The cover is off but the intermediate plate is stuck on. Next question. Is there a good machine shop...

    Chrysler 45 hp- change long shaft to short shaft

    why do this- if your only problem is getting on plane. Install a dolphin on lower unit as long as motor is big enough for size of boat
