My thoughts on a front and rear mount is this. If you have got a bigger than lets say 28 footer, which you have and you are putting the boat in bigger blue water I would seriously considering using a racing type front mount to angle plates bolted thru the stringers and a rear engine plate between the back of the block and the bellhousing and then also bolt this plate to angle brackets thru bolted to the stringers. This 4 point rigid mounting will assure the motor does not shift on stock Mercruiser type lord mounts. These mounts can allow the engine to shift enough under hard impacts and damage the coupler and drive alignment.
On the thinner wall blocks like the 496, we have actually seen quite a few cases where the shift is so large it punches the motor mount to block adaptor right thru the side of the block into the water jacket! Obviously, end of block!

Best Regards,

I`v got it and agree with you in your thoughts,but I got a little problem here,I do not like the stiff big plates of the racing mounts bolted right on to the stringers without any play,and I do not like the original Merc mounts, when the motors gets strong ,it must bee possible to make a more practical engine mounts to get the engines inn and out of the boats and for adjustments as well,something to think aboat ? Thanks,and have a nice day.

What about the jet boat type rail mount system. I think these allow adjustment.

The beast is breathing. I got the tail pipes in from IMCO and the were a perfect fit. I cut out my old 4" exhaust tip holes to 4.5" and installed the new tips. I fired the engine on the hose and she sounds sweet. I do not think my neighbors like it as much as I do . I need to mount a few small things, add a couple of more gauges, finish the revamp of my hood and I think I am ready for the lake.

Good looking rig. The motor with the carbon fiber accents looks great. One of my friends had the older 22 hull with a blackhawk drive. It would run GPS 94 with a bone stock 502 Mag. One of my favorite boats of all time. The thing was a rock at high speed. I'm sure that with the right set up yours will be good at triple digits. Congratulations, Eric

Well, I finally made it to the lake late friday afternoon. After running it around to check hoses, gauges, oil temp etc my buddy and I started doing some testing. It cruises at 80mph at about 3500 rpm. It accelerates like a mad man from any speed to any speed. The 1.35 gear ratio and the big motor made a completely different boat out of the 22. It planes out very easily and loafs along at 90 to 100. We made a couple of hard runs and it ran between 125 and 128 at 5800 rpm. I have a 120 mph speedo, so I am having to guess at the top numbers. I was running just enough trim to pick the bow up so, I think she will do 130 with no problem. I had one fitting that leaked a little oil, and it was starting to get dark so I will return next week. I have a video from his I-phone and a picture or two to post tomorrow.
It looks like all the effort was worth it
