    L6 Mercruiser simplified engine wiring

    by the way, if you re-organize the wiring and lay the parts out exactly like they are in the boat. you will realize you have the same number of wires and connections as the factory harness. you have simply overlooked the two connectors in the gunwale harness. the one back by the motor and the...

    Engine height on Offshore repower.

    with outboards, its more like 1" up for every 4" of setback (at least from reading on scream and fly) however you do need to test, and this is where a vertical jack plate pays dividends.

    Engine height on Offshore repower.

    Converting 5.0 mpi to closed cooling

    Dont worry about the motor. In 10 years the block will be rusted thru Yes, you already have too much salt buildup and rust to put an HX on To put a HX on your boat, you will need a new block and heads and intake. Run the boat as is, enjoy it as is, then sell it and buy a boat with an HX

    No Start, but should

    your distributor may be pointing to cylinder #1, however its pointing to it on the exhaust stroke, not the intake stroke. pull dizzy, turn motor over 360 degrees and re-stab on a 3.0, a few degrees advance will cause detonation under load.

    Little more valve lift

    buy the heads from GM and save a whole bunch of money. as in you get two heads from GM for between $800 and $900 (depending on sale or not) vs $900-$1000 for the exact same heads in a sierra box. you still need to modify the heads with thread-in rocker studs and modified valve seals to run a...

    No Start, but should

    First, your gauge is most likely bad if you are getting 200psi. 150 would be max for a new motor your dizzy is in 180 degrees out

    Little more valve lift

    unless you change the cam, the stock flat tappet cam from 1986 wont get you anything appreciable for power increase going to 1.52 or 1.6 now, if you change the cam, AND change the heads to vortec (requires an intake change). you can get some noticeable improvements. being a 35 year old boat...

    1972 Holiday seat replacement

    your best bet is to have your seats recovered. however being a 50 year old boat, you may need to completely rebuild them. not sure what you think a new seat should cost. today, a really good helm seat for a center console boat is about $1500 just the vinyl and labor that goes into a jump...

    Maintenance on garboard or brass plug that is leaking.

    first, never fill your boat with water. you now have water in areas that wont ever come out. second, pull the garboard plug. you will most likely find that there is an issue with the transom. for sealant, 3M 5200 yes, you always pre-drill holes. you also countersink the holes in the gel...
