    propeller issue at low speed

    Put the three blade back on and see if it goes away. Otherwise if hub is bad and it is a replaceable one replace it, otherwise send prop back for a new one

    Outdrive does not want to re -install in boat

    The drive and shifter are in forward and the shift mechanism is aligned full forward (in front of drive just below bellhousing)? If its in drive turn the prop CCW to ensure driveshaft is engaged with the Coupler, its shouldnt turn if it is. You might not be in the coupler yet and truning the...

    4.3 L Mercruser

    My neighbor had a cracked block after seeing a freeze plug pushed out. The point I was trying to make was I think in his case it took a couple of usesages of the boat (engine gettting hot and staying hot then cooling off) before the crack opened from water jacket to the crankcase. Im not...

    4.3 L Mercruser

    yes dodged a bullet, my neighbor had the same thing happen to his mastercraft a few years back. He got lazy it frooze then he winterized... core plug popped out. Intially he was ok but after 3-4 hard uses he started getting water in the oil. Bottom line just keep an eye on the oil for milkyness...

    Merc Alpha4 no longer available. What to replace it with?

    I think the rev 4 in general is an excellent prop but prop choice depends on your boat and how you want to use it. I get great holeshot, stern lift, and ability to trim out with the Rev 4. the pitch will depend on your boat and what its current engione/prop combo delivers in terms of WOT rpm and...

    Starboard riser hotter than port on 4.3L

    No set rule of thumb but what you should do now since it is running at proper temp is either with a calibrated palm or better yet an IR temp gun see how hot they are. That way you know what your engine when running cool is, down the road if you have issues you have a baseline of what good looks...

    Need instructions how to remove merc 2000 3.0 L Engine from Boat

    Let it hang, start your rear mount bolts, put your alignment bar in via the gimbal bearing, adjust your font mount and then drop it down. The exhaust leave until after the mounts are down and aligned. If I recall the 3.0 has a intermediate down pipe with rubber connectors on each end so you have...

    Merc Alpha4 no longer available. What to replace it with?

    I had 20 % slip with a vensura on my boat, but the slip allowed better holeshot as the engine would get in its power band sooner. chris seeing your results which mirror mine with vensura, you will really want to try a revolution 4 17” at some point. I lucked out and found an essentially new one...

    Pitch

    I wouldnt buy a prop until you verify current wot rpm. Current number will inform your need fir pitch Assuming your current prop is in the recommended 4400-4800 rpm range at wot, then go with a 17 or 18” pitch 4 blade if you want more holeshot. Going down in pitch will give more power on...

    Prop Blade/Pitch/RPM

    What was the WOT RPM with the 21"/3 blade? I would think a 19" 3 blade or 18" 4 blade like a michigan vortex would put you where you want to be

    Water Pump Question - Alpha 1 w/Closed Cooling

    Ball valve closes off the opening in the Y so you can flush it from the drive with fresh water or run it on muffs on the trailer , otherwise water pumped up from drive impeller will just push out of the water intake port. if the block never saw raw water you are good with closed cooling...

    New to Forum / New Boat / Selecting the correct prop

    I would reccomend a 4 blade for what you are doing - heavier load and fairly big boat for the power (22 ft/260hp). My general use is 6-7 people and go out for an hour of skiing,boarding, and then swim. I have found on my last two boats 4 blades work better for all aspects (holeshot, stern lift...

    1994 5.7L Weber carb

    None of that would affect idle, but those thise jets it would be slightly lean when running on the primaries and very rich when the secondaries kick in in my opinion start with the basics, clean and rebuild the carb, set the float level, go through the ignition components cap rotor plugs and...
