    Where to mount Smart tab SX's

    I would really like to put these on but the only place I have to mount them is right were the bunk stick out past the transom of the boat. I do not think that is the best place for them since it will band them. Does anyone have ideas on what to do for them?

    Gimbal Ring pin replacment

    I have a 88 Alpha 1 and need to replace the upper and lower pins. Should all the pins be replaced at the same time? I am looking at mercruiserparts.com and it asks if I have a splined or square upper pin. How do I know if I don't have it apart?

    Lower Unit Drive shaft movement?

    I put in a new impeller pump kit today and when I had the lower unit slit in two, the drive shaft that the impeller kit slides over has alot of play. Side to side, forward to back. I could see the bearing moving around as well under the spot where the impeller kit bolts to the lower unit. So...

    running warmer than it should be.

    I have been going over everything trying to figure out why it runs up to 185 or hotter unless I stop driving. It has a new 160 degree Tstat, and if memory serves me right I seen on iboats it should run no more than 10-15 degrees warmer that the tstat rating. It runs will not cool down @...

    1988 350. alpha 1 new engine new coupler new ujoints new gimble bearing Thought it was the new prop because I broke the new engine in with the old one and never ran it above 3500 for long periods of time until the break in was complete. Went from a 19 to 21 pitch and really noticed the...

    prop and hub question

    I keep seeing this hub and that hub, is the hub something that needs to be purchased seporatly from the prop or do all the props on iboats come with the hubs in them? for instance, the props for 1988, alpha 1 with a 350 in the 19, 20, 21 pitch range. 3 and 4 blades.

    alpha 1 gear ratios?

    Been reading about ratios, and it sounds like the 5.0/5.7's use a 1.5:1 ratio. I checked my outdrive and it is stamped 1.65:1. will running this ratio with the correct prop to keep the rpm's in the operating range hurt anything over time? how much does it change the way the motor operates...
