    More testing on Sharrow prop...

    And you have empirical Data to back that up? And if nobody has figured it out yet I love this prop. Just because it makes people lose their SH@T. Best prop EVER

    More testing on Sharrow prop...

    OOOOH MY GODDDDDDD here we go again. #1 There is absolutely a stock prop for a boat. That is why there are prop finders and Pitch is not a hard and fast rule. I have had a a 19" pitch SS Michigan wheel that my 70 hp could only pull to 5000 rpm. A 19' pitch OMC SST it could pull to 5800 rpm...

    99 Johnson 50hp 2cyl? Any good?

    Just the 2 cylinder motors had the weaker lower units.

    99 Johnson 50hp 2cyl? Any good?

    Not really you can find a lot of those with missing lower units.

    Minimum compression on 9.9hp 1986.

    Those were always cold blooded motors. I always grind the idle throttle stop back to allow more throttle for starting. Makes a huge difference.

    99 Johnson 50hp 2cyl? Any good?

    The 40/50/60 twins had weak lower units. If you find one broken more than likely the lower unit is the culprit.

    Prop Question

    Look at what Honda recommends for that motor and boat combo.

    That prop is for people with disposable income. What does the Merc equivalent of your prop cost? Then add lab finishing to it and It's not $661. You need to understand that prop puts itself in the range of custom props not mass produced. If you look at those prices they are more inline.

    SHHHH you want to keep this a secret. Some people here are still in the affair fog with their Enertia propellers. It's like bringing a Vampire into the sun has to be done carefully so they don't explode.

    Spark Plug Replacement for Mercury 115 4 stroke EFI

    On Amazon they sometimes use a stock generic photo of the item. As long as the #s are thew same you are good.

    Prop Question

    Racer is right about dropping pitch. Speed usually doesn't change that much because the lower pitch prop spins faster. I would also bet your fuel economy won't change much if at all because the 17 will be easier for the motor to spin.

    Minimum compression on 9.9hp 1986.

    My 77 15 hp with 90 psi starts fine on my cold duck hunting mornings.

    Need advice on power tilt for 1979 85 HP V4 Johnson

    1979 up until around 1990 will work, anything from a 3cyl to v6 will work. I would try to find a mid 80s 2 wire unit that uses the smaller relays. Try to get as much of the harness as possible especially the relay box. They are a direct bolt in so installation is fairly easy. Either take the...

    1982 90 hp evinrude will not remain trimmed out under power

    Yes 82 should interchange with a 1990 T/N/T, Look at how many wires come out of the motor to make sure. Look at the manual release screw on the side of the Unit. IF it is loose or has a bad o-ring it can leak by causing it to drop

    Minimum compression on 9.9hp 1986.

    Try a different gauge. I have a 1977 15 hp that runs fine with a hair over 90 psi of compression, I have had several that ran with that compression. What happens if you pump the primer ball when it bogs? Does pulling the choke out make a difference? Did you pull until the needle on the tester...

    Can I add an Oil Pump to a Yamaha CV85

    You need to get the parts schematic for the 90 hp and the 85 hp. The 90 came with oil injection and is the exact same block as your 85. Only the parts fiche will tell you if you can.
