Note: The Service Manual notes that all motor mounts for 5.0 and 5.7/6.2 are the same. Only difference might be where the mount ends up on the structure. I believe the trapezoidal piece my mounts are installed on is solid, and designed to take the motor mounts no matter where they end up.
As I suspected the mounting blocks in the hull are setup for varying engine sizes.
Will take some measurements this weekend and begin the preliminary to get the 350 in.
Please let me know how the boat responds. I'm highly interested in doing either this, or an updated 5.3L/327 once my 5.0L finally says it's had enough, or my bankroll grows inversely to my ability to not upgrade!
I've always felt a 350 or similar in this boat would make it an absolute beast, looking forward to seeing the results.
When I first had my boat out, it was equipped with a 17" vengeance prop. It would hit the limiter about 3/4 throttle. After working with my dealer, they gave me a 21" vengeance. That's the prop that would hit 53 mph on the gps at sea level. It was running 4800 rpm. The boat was limited to me 1/4 tank and no gear.
With more than 3 people it was a bit of a dog. I asked for a 19" vengeance and my dealer had their head service guy run my boat. After testing the various props I had run, he agreed the 19" was the way to go for how i like to run my boat. With the 19" vengeance, I can hit the rev limiter with 3 or fewer people. At the limiter it runs 50.5 at 4950 rpm's. It planes off with a full load, and runs plenty fast with the 19"
I am very happy with my boat, and thankful for all the support from my dealer to get it right for me.
@ jerry d
late chiming in on your engine swap questions but I did a 4.3 to 5.0 swap on my 2004 200 sport last winter. You are correct that your boat is set up for the v8 mounts. Side mounts are just approx 4" farther forward on the V8 than the v6.
When I did mine I dropped in the new engine, aligned the engine and drive, then used a 18" long 3/8 spade but to drill new holes in the stringers through the motor mount holes at a little bit of an angle. Used the same lags with some 5200 in the holes and filled old holes with resin. Really was quite easy.
I kept the 1.82 V6 drive instead of swapping to the 1.62 that normally came with 5.0's, but had to step up from a 19" prop to a 21". If you're going up to a 350 mag you may run out of available prop pitches or are you going to swap the ratio in the drive?
