    Help and clarification

    The 470's first year was '76. So who knows what you have in there. Post some pics Edit: rereading... Do you have a 4 or 6 cyl? Don't think there was a 3.7l 6.

    87 Mercruiser 205 V6 losing power past half throttle

    Yeah, pour the contents into a clear container to see what you get. All of those stores rent tools, some you wouldn't think of. I've rented flaring tools, bearing drivers, balance installers, drum brake tools (!) etc. AutoZone and advance don't have a time limit on how long you can keep them.

    1995 7.4 Thunderbolt starting

    I've been thinking about installing a momentary switch at the helm to activate the FP relay. Obviously won't work with a mechanical pump...

    Outdrive Popping

    How/why did the engine get swapped without removing the drive? First thought is u joints. See if it makes noise on muffs, then pull the drive

    1999 Tige v21 inboard mercruiser engine (acts fueled starved under load)

    Why would any mechanic swap out the pump twice and the fuel gauge before draining the fuel, filters and going through the carb on a boat that sat 4 years?

    Engine no power under load

    Do we know what carb we're talking about? Is op talking about the secondaries?

    Swap a complete 1988 OMC 4.3 out and put a complete 5.7 Mercruiser I/0 complete with wiring harness in??

    V8 seems a bit of overkill in a toon, no?

    Swap a complete 1988 OMC 4.3 out and put a complete 5.7 Mercruiser I/0 complete with wiring harness in??

    Same width, you'll need some extra room up front. Motor mount locations are different. Cut out is the same. You'll need a *complete* engine package, controls, wiring, exhaust, etc.

    Ford 302 alternator proper amp size

    A 1 wire can likely be used as well, though don't know your wiring specifics. @Scott Danforth , I assume the older wiring has all the helm power through the ammeter, which can't handle the increased current? I don't have a schematic...

    Trying to reprop, but how can I tell if my engine gets to WOT?

    Also, swapping the drive shouldn't have affected your throttle at all.

    Mercruiser Manual has a error in torque V6 Vortec

    Yeah, found that out after I snapped a bolt. We discussed it, starting post #153... https://forums.iboats.com/threads/nola-mikes-3-7-470-4-3l-swap-thread.720479/post-5463176
