    Approximate Boat weight

    I have a 14.5 foot trihull with about a 5 foot beam. I suspect the foam under the floor is waterlogged due to it's age (1969)and the boat seems heavy to me. The floor is glassed in, so It will have to be cut open to inspect the inner guts. What should the approximate weight be without the motor...

    Big Twin Lifting Ring

    Is it safe to lift and suspend my '69 40HP by the lifting ring on the powerhead? Is this what it's meant for, or is there some other purpose for it during manufacturing?

    Big Twin Retrofit Charging System

    Big Twin Crank seal

    Feeling ambitious I decided to replace my upper crank seal on my '69 40HP. After drilling two 1/16" holes in the seal I threaded two #6 sheetmetal screws into the holes and proceeded to tear the seal to little bits of metal trying to pull it out. Then I resorted to the tactic of wedging a...

    4200 RPM Att. Paul Moir

    Hey Paul, I hope you see this. I tried emailing You. I had my 40HP Big Twin out on the lake first time this year. Tach circuit works great. I can only wring 4200 RPM out of the motor. Butterfly appears to be wide open. First I tried a 10.5 X 12 prop, and only got 4000 RPM, changed after to a...

    Baltic Birch Transom

    I was thinking of using baltic Birch plywood to rebuild my transom. Very strong, rigid plywood with many plies. I was going to treat it with a boron additive to prevent rot. http://www.lectros.com/htm/02_timber.htm <br /><br />Has anyone travelled this route before?

    Painting an outboard gas tank

    Not sure what forum to post this under... I want to repaint the tank for my outboard, but I want to use a paint that is resistant to getting dissolved by the inevitable gas spillage. Any ideas?

    Big Twin Air Precleaner

    On My 1969 40HP Big Twin there is a precleaner for the incoming air from a hole underneath the lower motor cowl. Should this be regularily rinsed in varsol and have some #30 oil applied to the sponge like other small motors? If so, how often?

    Quick fix for trashed trailer

    I bought a 14' fibreglass boat motor and trailer that was generally not maintained very well for a good part of it's former life. The boat needed some TLC, the motor required some work, but wasn't beyond help. The trailer however, was in rough shape. someone had removed the tire from the rims...

    Spaghetti seal

    Where the spaghetti seal meets the prop shaft seal carrier on my big twin- is the spaghetti seal rubber supposed to overlap and be crushed tight against the O ring on the seal carrier? I am concerned I might have a slight leak here; I trimmed the seal flush with the end of the aluminum housing...

    Big Twin Prop shaft end play

    Is there any published specs for the end play on the prop shaft? I am wondering if I should shim up the back bearing race to pre load the tapered roller bearing.

    Big Twin seals

    On the new seals from BRP, they are a stainless/ rubber lip seal. Is the spring garter supposed to be exposed to the oil side or the water side for the driveshaft and prop shaft?

    Clutch Dog rebuild

    I have built up with weld (7018) and re-ground the worn ears on the clutch dog for a Big twin. Is this clutch dog cast? I am concerned about the weld chipping off when under shock and destroying the gears and bearings. It seemed to weld easily enough and didn't exhibit really high carbon content...
