    1996 Mercury 225hp 2 Stroke Carb - Loss of RPM and Top End Speed

    Make sure carbs are fully opening at WOT and TPS is set correctly. The 3L is bad about burning thru bleed lines because of stopped up/restricted check valves and only use OEM bleed line. A loss of 1K RPM is usually a cylinder dropped out. Check compression especially #6, check spark above 3K rpm...

    Suzuki DF25A prop

    Because factory props are inconsistent in manufacturing. You can take 4 new OEM props on same boat and get 3 different results. When I went for training at OMC in Waukegan this question was asked. Due to the wax casting process if prop line is delayed or there is a break/lunch the wax casting...

    Cylinder Compression Incongruences.-

    What did machine shop "polish" ??? Polishing cylinder walls will not reduce compression but extra honing will. Also increases cylinder wall to piston clearance and ring blow down thru excessive ring gap.

    1985 Black Max 150 No Spark

    Will make no difference to ignition. Only effects where timing marks are located Try cranking it with plugs removed,,,if you now have spark its starter RPM problem.

    External trim/tilt pump

    That looks to be a 1st generation 2L. I would add a few coins and get a later model motor. If you do decide to try this one dont pay over $500-700 for it and make sure you get matching control box

    fuel economy comparison

    It will burn 13 gallon of fuel at WOT reducing RPM will decrease fuel burn slightly. I have a 1980 150 Johnson on my 24ft Lowes toon. It good decent fuel burn below 300Rpm but sucks it up when towing grandkids on tube/skis

    Carburetor question on restoration I’m working on 1992 40 hp MSHQ Yamaha

    Back it in to water but leave on trailer, start and put in gear, slowly turn in the bottom pilot needle till engine leans spits , then back out till engine smooths out and add 1/8 turn. repeat for each cylinder. Multi carb engines need to be adjusted a tad different than single carb motors.
