    motor shakes when first started cold, how much should it move?

    I have a 140 mercruiser with a alpha 1 gen 2 drive. When first starting the boat after sitting for a few days the motor idles rough and shakes (kind of expected for a 4-cylinder with such big displacement I would think). How much movement is too much? I was wondering if my motor mounts might...

    help with boat pulling to the left

    OK, i took my first trip in a new boat tonight and it pulls to the left pretty hard. Hard enough that you have to fight the wheel and if you let go it would probably go into a spin. I read this: http://forums.iboats.com/showthread.php?t=250928 But it seems completely backwards? Is it right...

    floor flex around ski locker?

    the floor around the ski locker is not supported by the stringers. When I put my 200lbs on one spot around the locker it flexes down a little. It springs right back, I can not see any signs of moisture or rot. Is this normal or should I build some braces for it? I try not to stand on one...

    can someone help explain my tilt and trim situation

    I just bought a boat that has separate trim up and down buttons, and tilt up and down buttons. Every boat I've driven in the past always had trim up and down, then a single button (often labeled "trailer") that tilted the outdrive up. You would just use the trim down button to put the motor...

    what do you guys think, should I buy this?

    The guy agreed on $1800 plus my 1985 90hp johnson motor on trade. The guy said the boat is solid and the floor is good. He did say the floor had one soft spot but it was replaced in that spot and you'd never know it. The motor runs good but doesnt have an hour guage. It has a newer lower...

    19' boat with 3.7L merc, opinions?

    Im buying a bigger boat, and I may have found one. Its a 19' citation closed bow with a 3.7L 4-cylinder which is supposed to be 180hp. Its a one-owner boat and seems to be taken care of. I don't hear much about the 3.7L motors (mostly just the 3.0L). I wanted a 4.3L but this seems like a...
