    Tachometer for 1974 135hp

    Won't work. You need a 20 pole tach. They went from a 20 to a 12 pole in the early 90's Google 20 pole tach and see what shows.

    1978 Chrysler 85HP Powerhead Swap

    On the older stuff the gears aren't usually marked(unless your real lucky). You'll need to count the teeth Chrysler/Force used different gear ratios on all motors until about 90 or 91 Then they used the same gear sets on everything from 90hp-150hp including the L-drive.

    Odd running behavior

    Try the starting fluid test: start motor, spray starting fluid around the intake side of the motor. If the spraying makes a difference in the way it runs, then it's sucking air and needs work.

    Odd running behavior

    What's the rpm's in N ? Should be 750-800 in gear in the water. About 1100-1200 on the hose. Compression? These 2 cyl. motors can run on just one cylinder, make sure it's firing on both?

    1996 Force 120 with crazy compression numbers

    The factory doesn't really post the comp #s as they can vary so much. The later models were actually designed with the top/bottom cyl. comp lower than the two middle ones. The #s I remember are 155 #1/4 165 #2/3 I've seen the results as high as 175-180 on a 94 120 You sure it needs all those parts?

    YEA!!! I used an assortment of 2x10x12 blocks and just built them up to the right height. Left the Cobra in either gear f/r, it changes gear to N when it slides all the way in.

    Volvo Penta AQ140 water coming out of carbs.

    The 140 is 125hp 1975-79 The 130 is 110hp 1975-77 Should be an easy swap. If you drop to the 130 make sure you use the Volvo prop. They just work better.

    Looking to buy a 1976 starcraft holiday 21 ft. With a 165 6 cylinder engine. Engine is locked up,and was wondering if possible to rebuild that engine?

    It's a Mercruiser drive. Did a lot of Walleye fishing out of a 21 Islander. Try to get it unstuck before you buy any parts. Sometimes a couple days soak in MMO (marvel mystery oil) will help free the pistons. Worst case, remove the head, 4x4 and a 8# hammer. Start in the second and then the 5th...

    Alpha One Gen 2 Outdrive not going back on

    First your in the wrong section! Find the Mercruiser repairs a little further down the page. Second, the o-rings on the shaft, remove them and clean the grease from the groove. Then reinstall and grease only the top of the o-ring. Too much grease under the o-ring lifts the ring and makes it...

    Force 125 1988 Water drains out the exhaust

    When using the hose direct to the copper tube, the regular house pressure isn't enough(most cases) to activate the pressure release. The impeller/pump can pump a LOTTTT of water, usually more than the hose can produce and in the water you have access to millions of gallons and the hose comes no...
