agree, no way that 4000# dry weight boat is going to do 50 mph with a 5.7 unless the 5.7 is in a truck pulling it down the highway
with the boat being 25-26 years old, time to look into a few things.
have the boat weighed. if you are carrying extra weight such as saturated flotation foam...
going to any drive from your OMC will require a new transom and stringers. at that point, you can go to Mercruiser, Volvo Penta, Ilmore, etc.
current motor location / mounting / etc. is specific to your OMC drive, its intermediate housing, etc.
your motor and drive will weigh in about 750#
your hull without motor is about 700# from what I found.
then add weight of battery, fuel, gear, etc.
the bunks should just pass the transom
there is no shredder that I know of, however i used an old paper cutter and a 6-pack of beer to spend an afternoon making a bucket of cut fibers to make some hairy PB
Agree that the crank driven raw water pump will work better than the mercruiser one. Cant beat the carter universal marine fuel pump, relay, and oil pressure switch for the fuel pump as well.
Will also caution you with the Stainless Marine elbows. if you have any overlap to the cam, the short...
you do not have adjustable valve train. so you DO NOT GO 0 LASH PLUS 3/4 turn
with the adjustable valve train your heads are setup for, you bring each cylinder to top of its stroke and run the nut to the step in the stud, then torque to 27 nm. or simply run the nut to the stop on all...
unless you sand blast or cut out the rust, there is no effective "rust remover" in a can
also, dont even consider stuff like POR-15
unless you dip each piece and install them wet, then dip the whole trailer, there will always be a gap. the frame flexes, the fenders move. the joint will still...
if your rocker studs look like this, then the head is set up for non-adjustable valve train. you tighten the nut until it bottoms out and then torque to 20 ft-lb (27 Nm)/ you have just a nut and the rocker on a trunion
if the rocker studs look like this, then they are for adjustable valve...
with non-adjustable valve train on the 4.3, just snug up each of the rocker fulcrums to the stop location on the stud. then torque to 20 ft-lb (27 Nm)
you get a better torque reading if each cylinder is brought up to TDC on its own. however with non-adjustable, I just zip them on with the...
let it wander...... it will zig-zag a saw-tooth pattern in a straight-ish line. all single propeller V-hulls wander. its the side thrust of the prop pushing the tail end out until the rudder forces on the leg push it back.
look up v-hull wander
as others stated, most people fight it and make...
