use a mirror on a stick.
every component with a pulley mounted to it is responsible for belt alignment. only the power steering pulley can be adjusted in/out with a power steering pulley puller
your 2000 vintage should be serpentine belts. the belt tensioner is a spring loaded arm with a $3...
welcome aboard
could be shift cable is no longer shifting
could be broken shaft like stated above
could be stripped gears in the upper
could be damaged dog clutch assembly
cylinders 1 and 4 are low, however not terrible.
put a mechanical gauge on the motor to verify oil pressure. do not rely on a 33 year old $3 gauge and $5 sender
1200 hours on the boat is about like 50,000 on your car with maintenance your motor could last well over 4000 hours
look at your...
What did your builder balance the assembly to? Zero?
What are the bearing clearances for rods and mains? Did you go with coated bearings?
Stock pistons, or hypers or forged? Flat tops? D-dish?
Cast or forged crank? Cast rods, or H-beams? Cast or billet flywheel? Stock damper or sfi 1.1...
get the motor running ASAP
you may need to replace the wiring in the boat. maybe not now, however within a year it will all be corroded. they did not used tinned marine wire back then and the water will have wicked up the wire inside the insulation.
the boat is the least of your worries...
You underestimate how shoddy the work actually is at SeaRay. its not any better at other boat manufacturers. and that is today
Boats in 80's were worse as that was an economical boom that had everyone and their cousin in the boating manufacturing world slapping these things on their butt to...
The early mounts are "squishy" and the original rigging may have been done with a 2x4 to pry it in place as they ran the lag bolts in with a burp gun.
You may need to epoxy in some slugs of wood in the old holes and redrill new ones
Here is my take
that is a lot of boat for that wee little V6. just looking at dry weight you are at 16.8#/hp , you are at you are trying to push a lot of weight ..... compared to the 130-140hp with the 1600# 16.5' Avanti i had (12.69#/hp) , or the 220hp for the 19' 3000# SeaRay 190 I had...
first, welcome aboard
second, get a factory manual for your motor and drive
third, there is no searay manual for the boat, they dont exist.
regarding your bimini, see your local canvas and marine upholstery shop.
you have to re-stab the distributor properly. when inserting the distributor, the rotor will turn as the distributor is installed. make sure to have the rotor pointing close to the #1 cylinder tower on the cap (just get it close, you have to set timing), and the distributor will sit a bit...
I wouldnt be beaching a pontoon with an IO if the drive is not in deep enough water to trim up.
the prop is the least of your worries, burying the drive in the muck and sucking muck into the impeller taking it out should be your worry.
as racerone pointed out, you need a depth finder
