    Help me identify what engine I have in my new boat

    Volvo Penta put 715CFM carbs on stock block 350's from 1987-1994. the AVS 2 along with the webber and the 1409 all are available as 650 CFM or 800CFM. since they have the secondary flap they only flow what the engine can draw.

    the current carb sounds like the idle circuit is plugged and you are only running off the main jets

    correct, you can not make a 3.0 distributor fit a 3.7 short of a machine shop and custom make one. the 3.7 liter does not have an electronic distributor anywhere. the only thing that exists is the pertronix point replacment trigger, however the distributor still has the mechanical advance...

    Skinny water day.

    Some co-workers run in 1-2" with their custom flats boats. They are tunnel cats with a jack plate. Once on plane, you raise the motor all the way up and just skim the surface

    Just thought I'd share a nice photo.

    It's also compounded because the gear should be almost twice as large for the loads we are seeing in order to use cheaper materials....... Because sales wants smaller....smaller....smaller....more power density

    Yes, two shortcomings, one was improper material for the gear, and an issue with induction hardening of the worm

    Testing Gas Flow on 82' Wellcraft Sterndrive

    failed heat treatment on the worm allowed the teeth to deform and wipe out the teeth on the wheel. Additionally, centrifugal cast C91700 was spec'd and the vendor used sand-cast C91700 which is about 60% the strength. so the worm wheel failed sooner than it should.
