My suggertion to is to replace them both,if one goes the other is usually not far off to go also..if you replace one the new engine will run stronger then you will find your self staggering the throttles to compinsate for the stronger engine..Gm performance parts makes a 330hp sbc that will work great for your application..when i install them i replace the oilpans with a moroso 7qt because the pans supplyed only hold 4.5 qts of oil.....then i purchase a vortech style intake and a lifter valley splash guard to prevent the oil in the lifter valley from splashing and heating up the bottom of the intake.....

the last boat i did was a 22' celeberty with a 260 and did 48mph,after the engine swap the boat did 55mph and is has 200+ hr on it with no issues....at the time i think i paid 2400.00 for the engine
