not sure what the issue is with the cylinder sitting in the water. not ideal, however thats common.
how old is the boat?
if you have water soaked foam you could be sitting 2-3" lower in the water than you would if the hull was dry.
when was the last time the boat was weighed?
remember, recreational boats are designed to last 15 years and be replaced or re-stored.
fiberglass or aluminum boats get rotten structures, wet foam, stress cracks and soft surfaces deteriorate. plastic thru-hulls fail between 5 and 15 years.
you may want to check the gauge. any reading greater than 150 is suspect or there is water or oil in the cylinder. a brand new engine from mercruiser or volvo penta or GM will have 150psi as cranking pressure
with a dual plane manifold, only doing one bank would also be suspect.
with a dual...
as you raise the motor and the anti-vent plate comes above the bottom of the hull, you will eventually ventilate as you apply throttle. from what I see, your motor height is perfect.
15 years before the wood turns black it would have been saturated with water
read some of the resto threads. both exterior grade and marine use the same glue. the wood is a slightly different species, however both will rot when exposed to water....... which is where the encapsulation comes in.
being a 1983 anything, much less a disassembled cluster of a project, check the transom, stringers and deck for rot and the flotation foam for water saturation. I would do this prior to even worrying about where to put anything because there is a reason the boat was torn apart and then passed...
you still have not answers why you need it.
as I stated, with the sunbrella bow cover on you can literally plow into a 7 foot wave at 20mph and the wave will wash over the canvas, up the windshield and land on your head. This was done with my SeaRay 190 often
at slower speeds the water will...
not sure why you would add something that ugly to the bow of your searay. the standard bow seating cover suffices in keeping water out of the bow area if you take a wave over the bow in 7 foot rollers.... BTDT and have the tee shirt. it will however slide the water up and over the windshield...
my guess is that the elastomeric sealing strip between the keel and hull is damaged or your keel itself is leaking.
pouring water into the keel V trough will run to the back of the boat. that is what its supposed to do.
yes, the boat is riveted together with 2 sheets of aluminum and a formed...
clean all your battery cable connections from the battery to the block and starter and back.
by clean, they need to be shiny enough your mother in law would eat off them.
buy a jack plate. that way you can raise it for mooring and then lower it to use it.
if you raised the motor 6", you would never get on plane, and even though the pickup ports are below the water, the water pump wouldnt be and it would never prime and you would toast your impeller the first...
since your boat is a 1990, you either have a Mk IV motor (2-piece RMS, flat tappet cam) or a Gen V motor. if its a gen V i would recommend upgrading to Gen VI (1996 and later) the 1990 Gen V blocks are the first year of priority mains oiling and there were goofy issues with the steam holes and...
