    Shift cable 67 100hp merc

    Last fall I purchased a 67 100hp merc Tower of Power engine that would not go into reverse. This winter I removed the lower unit and could not find a reason for not shifting. I replace a worn shifting cam, reassembled the LU and it seems to work correctly. Because I didn't figure I would be able...

    1969 Tower of Power lower unit

    Last fall I purchase a 69 100hp Tower of Power with a bad lower unit. I have a 66 100hp and figured if my power head died I could just switch out the lower units. Since it has been cold and I didn't want to work outside I decided to look into the bad lower unit just out of curiosity and thought...

    Roller weight

    How much weight should the center rollers of the trailer be carrying. I recently adjusted the height of my bunks so they were each sitting the same height and it took the weight off of the rear and second roller from the rear. That made me start wondering how much weight each of the center...

    1969 Tower of Power

    I have a 1966 100HP and have been looking for a parts motor just in case!! I found a 1969 100HP Tower of Power that ran good this summer until reverse went out. I know the ignition system is different but I was thinking if anything major happened to my 66 I could put my lower unit on the 69...

    Yamaha prop

    Have a friend who has a prop from a Yamaha motor. It is the same size and pitch and number of splines as the one on my old 100 hp Merc. Will it work on my motor? It looks like new and he said he only ran it for a few hrs on his 115hp Yamaha. Thanks

    Serial number

    Can someone tell me for sure what year and model my motor is? By the serial #1893776 and looking for parts I have found it listed under 95 and 100 hp. and 1965-1969. Many times I can not find any part listing and I don't know if that is because it is the wrong part or there are no parts...

    1967 100hp merc

    Went to look at a very clean 1970 17' Starcraft Riviera today. After looking it over the owner said if we could hook it to my truck, we could pull it out of the garage put the muffs on it and start it up. Long story short it would start but not keep running. About 30 frustrating minutes later...

    Starcraft

    Has anyone had experience with the old Starcraft boats that had the high impact plastic Hulls. From the looks of the pictures I would guess it is from the 60's. Curious about how they held up. Thanks

    Shear pin

    I have a 1967 65hp 4 cyl. merc, question is, does it have a shear pin installed somewhere? When I bought it last month the father of the man I bought it from told me to always be sure I had extra shear pins and in cleaning the boat I found a bag of them. I have pulled the lower unit and changed...

    Carb removal on 67 650

    I want to rebuild the carbs on my 1967 65hp merc. In looking at the location of the carbs there appears to be a lot of electrical that needs to be moved or removed in order to reach them. Is there some secret to moving wiring around in order to make access easier? Also is there any syncronizing...

    early 80's 65hp merc

    Went to look at an early eighties 65 hp engine today. The compression was 100,100,105,100 so that looked good. When I pulled the gear oil plug on the lower unit it was brown and obviously had moisture issues. It shifts good and does not make any noise nor does the prop shaft seem to have any...

    66 Dorsett with mercruiser outdrive

    First time poster. I have a good friend with a 1966 Dorsett boat that has a 150HP Mercruiser engine and outdrive. The bellows boot leaked and over the winter (3 years ago) the gimbal bearing rusted to the drive shaft. The boat is overall in excellent condition and I can pick it up for next to...
