    How do I get the windshield off my old Crestliner Muskie

    I am trying to take the windshield off my old 70ish Crestliner Muskie. It is a rather typical looking flat plate aluminum channel bowrider setup with the two triangular panes on the sides.

    I have a '79 Johnson 140hp manual shift with a siezed power head. Is it possible to swap the power head from a '72 Johnson 100hp electric shift onto it? Would it be the same block?

    siezed '79 Johnson 140hp, advise needed

    Yesterday purchased a boat with a siezed '79 Johnson 140hp. Motor will be winter project. The PO couldn't help me much as to the cause of the sieze. First boat for them and first time they had it on the water. I'm guessing they didn't mix oil with the fuel.:eek: Mild mannered...

    where does the gray wire attach and what is it for?

    '72 Johnson 100hp (100esl72r) There is a gray wire that exits the main harness in the motor and dangles near the terminal block. The boat has a tach but it doesn't seem to be working. Could the gray wire be for the tach? Where should it attach to the terminal block?

    Where is the "pee" hole on my '72 Johnson 100hp 100esl72r

    I haven't had it in the water yet. I want to ensure the impeller is impelling before I do that. When I put the muffs on it water comes out a small hole high on the port side of the LU and a small hole low on the starboard LU. It also leaks over the top of the LU. When I run it on the muffs...

    1972 Johnson 100hp carbs with no mixture screws?

    Ok, So I tore the carbs apart on my "new" 72' Johnson 100hp (100ESL72R) to clean and adjust mixture screws. I do that to all my engines as soon as I get them. But, I didn't find any mixture screws. This is especially surprising considering the air induction cover has 4 holes plugged with...

    power tilt wiring question

    I have recently aquired an old boat with a 72 Johnson 100hp with power tilt. There are three wires coming out of the power tilt. Two go to the tilt control on the dash. The third is black and has a battery cable connector on the end. Is this a power wire or a ground wire? Thanks

    I just had a boat with a Johnson 100ESL72R engine given to me. It was given by someone who wanted the boat gone so he could sell the trailer. Lucky me? Let's reserve judgement. Yesterday I put on the muffs, hooked up a good battery and turned it over. It fired up but runs a little rough...

    1971 evinrude 50hp model 50173s idle

    I have recently purchased this '71 evinrude 50 model 50173s. It was not running when I got it because the throttle cable was broken and the ignition switch was jamming. I have fixed that. The engine starts easily and ran well when I took it for a slow cruise around the bay, but stalled every...
