    1986 Johnson 25hp "Slips out of gear at high rpm"

    Brushy lake is in Bankhead. It has a 10hp limit.

    To prop or not to prop (or motor)

    $70 plus whatever you can get for your 15 right before duck season might get you pretty close to a 25. IMO the 31.8ci OMC was one of, if not the finest outbaord ever produced.

    48SPL Stops Making MPH Before It Stops Making RPM

    Thanks for sharing that, good to know there is a steeper prop out there. My motor has brackets and OMC accessories trim switch, and wiring, I was told this used an electric actuator, I have not been able to find any further info on it though.

    48SPL Stops Making MPH Before It Stops Making RPM

    If I ever touched 35 I would be tickled. I do have a real nice 70 that I thought about swapping before I replaced the carbs , I thought maybe it would hit mid 40's then. Overall I am happy with the way the boat runs now, I haven't tried but I think it would pull up a skier as is, and planes...

    1986 Johnson 25hp "Slips out of gear at high rpm"

    That's good to hear about Catoma, now I can stop looking for that 9.9 cowl for my 15. I may still need it for Brushy though.

    Tach ordered. Not a shear pin prop. The Michigan features a user switchable hub, which means I can replace just the metal part of the prop and save $25. Just wish they made a 19p.

    1986 Johnson 25hp "Slips out of gear at high rpm"

    The 86 didn't have the clam shell case anymore. And the shift forks are nla. More important where are the 25hp lakes down there, the ones I know about are 10hp max. I do remember seeing a big ole motorwith 9.9 decals on cl awhile back.

    Johnson 25hp question

    Most boats I have had w/o trim run best in the second hole. If you are in the first the motor is tucked under.

    48SPL Stops Making MPH Before It Stops Making RPM

    I do need a portable tach, any recommendations on one I could easily move from boat to boat? Maybe a tiny tach? I am concerned that I may have moved the power band of this motor by switching carbs and not the exhaust housing as well. OMC introduced this motor as a 100:1 premix, and were jetted...

    Would you run this prop?

    Back it and smack it, run it. If you can find a brand you may be able to buy just the prop and re-use your hub.

    48SPL Stops Making MPH Before It Stops Making RPM

    Anti-cavitation I should have said. There is no tach, but I have had enough boats with them to know what sounds right. This one is going a little past right. Normally I would just get the next wheel size up and see if I could turn it, and I think this one would if it was out there. The prop I...

    48SPL Stops Making MPH Before It Stops Making RPM

    I don't know why you are yelling at me, but I do understand rpm's do determine pitch, but there is no higher pitch prop that I can find. One would think though that as long as the motor is gaining rpm the speed should also increase. Now if the carbs I have now are from a more free flowing leg...

    48SPL Stops Making MPH Before It Stops Making RPM

    Long story short I bought a boat with a 1987 48spl, upon opening the throttle it would bog, then slowly build rpm and plane off in probably about 8 or ten seconds. Brought it home pulled and cleaned the carbs, then noticed as I was putting it back together it had 2 very different bore sized...

    Working With Aluminum

    The material I have is about .070 and it maybe too thin. I know I can make straight cuts with the squeal saw, it's those curves in the bow, and around the ski hole I was not sure about, I do have a jig saw I'll try that. The stuff I have has about a 1/2 inch turn down on one end and since it is...
