I have done my own boring at friends workshop.----Cost me $25 / hole + set of honing stones and my time for the work.----Pistons / rings and gaskets.----Most bearings can be re-used based on my experience !
Had a panic call from a dealer.-----Looking for a rebuilt block.----Did the job for way less that what you are spending.---Dealer gave me an extra bunch of beer tokens as well.
$2500 and you are doing the work yourself ??-----Way too much in my opinion.----Many times the pins just slide into the new pistons.-----Heat the old pistons to make the pins fall out !
It depends on what boat the motor is pushing.----You need a splined prop and one that does not have through the prop exhaust.------Post part # of some props that you are looking at.
