Adding that much power I would upgrade your front motor mounts to solid offshore mounts directly to block. As far as props, what rpm's do you plan on running the 540's? My 353 fastech ran 5200 rpm's with labbed 31's on 500 hp's. (a little over 80 mph)

supercat, I am upgrading to (3) 1/2 inch stringer bolts per pad with solid stock style mounts from Eddie Marine if you or anyone else thinks that is not sufficiant nows the time to change things. Where do I look for true offshore mounts? As far as props the engines are supposed to redline at 5400 I was planning on trying some 30 & 32 pitch 4 blade bravo 1s to test & get a baseline & go from there. Randy

Looking at your pics, I think your mounts will be adequate as long as you have backing plates on the other side of the stringer. They are pretty much a combination of the adjustable mount and true fixed offshore style mount.

They have large washers on the outside of the stringers but I do have the material to make plates if needed. Randy

Got some paint put down today, what a difference! I am not stripping everything Im going to tape around the transom plates these pics show just the floor but I have the starboard half painted with 1 coat the floor has 2. How many coats should I put down? I mounted some lights while in there & they are cool. Engines & exhaust are on the way, will update when more is done. Randy

Looking great. Keep up the good work. Artie

Got some more painting done, if anyone ever tells me a body man/painter doesnt earn their money they might get a punch in the mouth,LOL even with all of the sanding I have done it still isnt really smooth but shouldnt be a problem as the water just beads up on this paint.

:party-smiley-048:Engines & exhaust were delivered today I guess I had better get busy

randy,engines look good,did you get them from a member on oso?

Not sure if he is a member but they were advertised in the classifieds. Bullet Engines, Ontario,Canada. He is very easy to deal with & does a nice job these things are ready to drop in & go. Seeing them up close they are purdy!!!! Should look even better with new CMI exhaust I got setting in my garage. Randy
