There should be limber holes from the tank compartments to the bilge but none on the flotation. It just dawned on me, but at least on the older boats, there was no access to the flotation compartments. They were glassed closed.
It's not unusual for the weight to be a couple hundred pounds per side. If only one side we're saturated, it would list pretty good. One member reported taking both sides apart and said the foam weighed 350. Not sure how he weighed it but I took the foam out of an old Evenrude boat and it...
I used Gary's tree method. But had to use two trees because South Jersey trees are small. Two harbor freight nylon straps strung between the trees and a cable come along for the lift. Had to move the trailer under and away .
Met with Bob and when I left the marina, it looked like he had it well in hand. I enjoyed my visit with Bob and his daughter Kaity. Nice people for sure. The boat is a good looking boat for it's age. Someone took good care of it. I hope to get to hang out again with them.
The fresh water option was available but cost more. I think from my conversation with Bob, he has a FWC. What it called a half system. The block is antifreeze cooled but the exhaust manifolds, risers, transmission heat exchanger, and raw water pump are raw water cooled. All systems have a raw...
This is from an old thread by Nay who was one of the original Shamrock employees:
So a 20 footer would use appx. 60 ft. or so.
The trick we used to install the rope in the rubrail was to get it warm first (like Tony said) but, and here's the trick, get...
if the engine back fires, has what's called valve overlap(where the exhaust valve and intake valve are open at the same time), a pin hole in the water jacket and if you back down and water is forced up the exhaust are some of the reasons.
the 20s get squirrely at 35 to 40 if you keep the bow down. some call it keel walking. if you raise the bow up it reduces the keel walk. the old 302 was rated at 4400rpms at WOT. the rollers might have added 2 or 3 hundred rpms. displacement might have added another 100 if you went with...
a compression test will tell valve rings and overall condition of the engine. use both wet and dry methods. it's a standard look at new boat engine so it shouldn't be a problem with current owner. if it is, figure engine is toast.
