    Volvo Penta SX-M upper compatable with DP- SM lower?

    Anyone know if the SX-M upper will work on a DP-SM ? Both were behind 5.7l engines. The SX-M upper i found is advertised as a 1.60 ratio. My DP-SM lower is a 1.95 or 7.

    Volvo Penta duo prop what props do i need?

    How do i choose props for this out drive? I bought it on craigslist with out props. It came off of a 22' stingray with a 350. I'm putting it on a 20' Glastron gs205.

    Pros and cons? Not much porting if any to do on the raised runner eq head. Small ports should be great for volicity and fast burn chamber a + ?

    Which vortec heads for 383 build

    I see different vortec style heads new with different sized valves and runners. Some are advertised to out flow the stock vortec heads. Some have the 170 and 185cc runners with 2.02 and 1.60 valves. Would these heads be OK for a 383 build? I plan on running stock exhaust system and my outdrive...

    Engine question on my 98 Glastron gs205

    I'm not sure if this is the right forum to ask but here i go. I bought my 98 gs205 with out an engine and am currently looking for one. Would a 400 small block work in place of the 305 vortec that was in the boat or is the flywheel differance going to kill that idea? My drive unit is an sx cobra.

    Clear gel coat for scratches?

They're not down to the fiberglass but deep enough that it will show up as waves in the gel coat if i...

    What year engine?

    For a 1998 Glastron GS205? I bought the boat last week with a missing 5.0 I plan on building a 5.7 to put back in it and going with a new marine cam.

    1998 Glastron GS205 SF question

    I bought this boat yesterday as a project boat. Does anyone know how much clearance there is between the carburator and the engine cover? It came with out an engine so other wise i wouldn't be asking.

    Stringer spacing on 1998 Glastron GS 185

    I just bought a 98 gs 185 with a 3.0 engine. I know these same boats came with different size's of engines. Are the stringers on each side of the engine where the engine mounts bolt up to them spaced the same as my boat that came with the 3.0? I'd like to put a v6 in it but not if i have to run...
