I have a 1994 Mach 1 2900 Endeavor with twin 454 mags (365 carb). I bought it last year for 18,500 and still owe 16k. its in good shape (except the engine). The shop is telling me that water is getting into the cylinders both sides and I probably need a new engine... The shop has told me that the cheapest they have found so far is $7k; they are going to keep looking a bit but its not looking good for me and my wallet. I have already conceded to the loss of this boating season. So, 7k and im back on the water next year with the shop doing all of the work... or is there another route to take? This is the thing... the both motors have almost 500 hours on them and I am afraid that even though the other motor is running fine I don't want to loose two seasons in a row... also I would like to go much faster than the 65 mph I'm running now at 4250 rpm. should I repower? or just replace the one engine.... maybe rebuild the other? I want to go faster but I know I have to pay for it... I have a little knowledge about mechanics(nothing to brag about) and have alot of time (obviously none will be spent on the water) and plenty of desire to learn as I would love to do my own work... Please!! any and all advice would appreciated! If you have a idea... lets hear it! even if you think I should sell the boat the way it is and find another boat tell me what you think.
