    94 Kawasaki 750ss

    I just bought the above jet ski and it runs wonderfully except for the fact that if you try to put 2 people on it it wants to turn over. I don't know if this is the nature of the beast or if there's anything that I could do to correct this problem. I don't know if I could add any foam...

    WOT Only 4000 RPM

    I have a 1974 Starcraft 15' runabout trihull with a 1977 70hp Mercury. I am using the prop that came on the engine, and I do not believe it is the correct one for my boat. I bought a Mercury tacometer harness, a universal tach from bass pro, and had the engine rewired. The tach only shows...

    175 Black Max Won't Run When Cold

    My fishing partner's 175 merc black max will not run when it it cold. By cold I mean not only engine temperature but also air temperature. Early in the morning when it is first started you can press the gas to the floor (hot foot) and it boggs like it is blown up and will not plain off...

    Keelshield and Rollers

    I have a 1974 15' Starcraft trihull that I want to install a keelshield on. My only problem is that I have a narrow wheelbase trailer with 8 in wheels and tires. My trailer has several rollers along the keel of the boat and two short bunks. Two of the rollers are in the way of installing my...

    Smart Tab Help

    I had a big problem today when installing my smart tabs. I sealed it with the sealent foam tape and 3M 4200. The instructions said to drill 1/8" pilot holes and I think I may have misread it. However, that's what I did and when I tightened the first screw it seemd a little tight. So, I...

    Sealing Smart Tabs

    I am about to install smart tabs on my boat and I'm not sure how to seal the holes for the mounting screws. I don't entirely trust the tape so I plan to use the tape plus a sealer. I don't plan to keep the boat for over a 5 year period and I may plan on removing the tabs if I do sell the boat...

    Will this work?

    I found this tachometer http://www.basspro.com/servlet/catalog.TextId?hvarTextId=37068&hvarTarget=search&cmCat=SearchResults at bass pro shops and I wondered if it would work with my 1977 Mercury 70 hp (newer powerhead with powerpack unsure of year). It puzzles me that there is no selection...

    Mercury 150 Black Max XR2

    The last two trips out this motor has given a lot of trouble. It does have oil injection, but since we've heard that you can't trust the system we put 16 oz of oil into the 12 gallon tank to act as a back up incase the oil injection stopped working. So, the engine was recieving oil from the...

    Wiring Harness

    I have a simple question about tach wiring. I bought a wiring harness that matches my control box and tach. It has three wires white, black, and brown. Could anyone tell me which wires go where. I think that Black is ground but I'm not sure how to tell the difference between white and brown...

    Oil Leak?

    My motor is a 1977 70hp Merc and yesterday when I changed the motor from one boat to another that under the cover is very greasy and oily. This is mainly on the port side of the engine block. The guy that switched my motor works on OMC and says that he doesn't know much about mercs but he said...

    Power Trim

    This is just a stabb in the dark, but I was curious if power trim is somewhat universal. I have a 1977 Mercury 70 hp 3 cylinder. Unfortunately it has no power trim, just the two little shocks on the back. I would like to add power trim to it, but I was quoted a price of $350 for parts to do...

    150 Gas Mileage

    I'm looking at a 150 hp mercury in the paper right now and I was wondering if it would be a very big gas hogg or not because I heard that these motors should get about 5 miles per gallon if you hold it at about 3000-3500 rmp on a lighter boat (so is this true?). The add says that it's an older...

    Hydrofoil

    My grandfather owns a 1983 Norris Craft fish and ski boat. Even though it doesn't belong to me I use it with him every time that he goes to the lake. But the boat has a problem with the ride. Even though it is a fish and ski boat it actually has the same hull as the same length (17.5 ft) bass...

    Three Blade Prop

    I have a question about going from a three blade prop to a four blade prop. We have a 17.5 ft Norris Craft Bass boat with a 1986 Mercury 150 hp XR2. Currently it has a 23p three blade Quicksilver prop on it and will turn 5800 rpm. We found a loner prop from a family member to try, but it is a...
