    Everything done but low rpm at WOT. Distributor spring?

    Full revs in Neutral means Eff all. The engine is not under Load. It is a great way to throw a Rod, due to the very high G-loads suddenly imposed on the Rods and Pistons. Did you check the Y Pipes and the Exhaust Bellows?

    . . . and I Thought Hi-tech Boat Engines Were Bad . . .

    A couple of Friends have or have had Beamers. One got his in the early 80s, and for a Couple of Years really liked it(why I have no idea, as I thought it was a POS). Once the Warranty ran out, he started disliking the Car. A couple yrs later, his Kid managed to Roll it on a City Street(never did...

    Everything done but low rpm at WOT. Distributor spring?

    Sorry. I wish the Site, could provide an Identifier, for the OP, cause after many posts/replies I get confused. I will edit/delete the post More Blade Area might help. Have you ever checked to see if the Exhaust Pipes are Clear? If the damn engine can't Exhale...

    Lower Unit Gear Oil Running Temp ?

    All of the Outboards and I/Os. myself and Family have had over the last 60 yrs have been kept outside in temps that have dropped to less than -35. Never burst any Seals. What in the world does having a temp sensor in the Oil do, that having a Thermometer next to the Gearcase wouldn't? Get a...

    40 hp johnson electric shift Model # 40ES 69R

    If you don't want to change the oil a couple of times, you can just let it drain for a day or so, then refill it with the Precision Blend. I am a bit more concerned about mixing oils than racer... but that is a personal choice

    How to find pitch and diameter of a stainless steel prop and is it left or right

    OMC coated their Stainless Props with Teflon, simply to hide rusting, and Teflon sounded Cooler than Black Paint. Maybe it was to imply that water wouldn't stick to the Blades...

    . . . and I Thought Hi-tech Boat Engines Were Bad . . .

    Is that the infamous 3.6, with Elastic Timing Chains? One of my Caddies has that engine, and the chains were supposedly changed under warranty a few years back. Rotors and Pads are aren't too pricy, but the rotors are throwaway items

    What is that hatch in the 2nd Picture about? Remove the Engine cover, is there water in there? Without seeing the entire Boat layout it is very difficult to make any Diagnosis, as to where water could be coming from. Carpet, can hide a Multitude of Sins

    40 hp johnson electric shift Model # 40ES 69R

    The proper Oil is marketed by BRP as Precision Blend. It used to be called Type C. Be aware though, that there are some 3rd Party Oils claiming to be Type C, but are not Compatible with Electric Shift . The proper oil is less Viscous than 75-90 gear, being that there will be some residual Oil...
