Is this the boat that sat at Lake Cumberland for YEARS?! Always liked the idea but heard it was a bit of a handful. It was there back in '05 when I ran the two ilmor talons that were also there.
Have your buddy talk to ilmor about doing some upgrades. The 550s were pretty old school compared to what they are doing now (dress and power). Believe these had the coolers in the rear if I'm not mistaken.

Since when?!
Tell him to get used to the boat. With the low hours I bet its the same one I'm thinking of. Seem to recall the boat was a bit squirrely at speed. Im sure even if it is it could be worked out (if it hasn't already). Rik on here may be a good one to touch base with on this particular boat to be sure.
Have a blast and be safe!!!
(btw bern I still owe ya details on my triple trailer, shoot you an email tonight)

The water pumps on the 550s are an old design than what Ilmor uses now. But I have had no problem with them. If the boat has been in salt water and they werent flushed immediatly they corrode on the inside and the bushing that holds the shaft wears out and causes the impellers to premeturely wear and fail. I replaced my housings and they work great. If you take the impellers out and they have broken apart the rubber pieces will go through the housing and plug up your coolers. Usually the first cooler after the water pump. But I found pieces in both the oil cooler and the engine coolant cooler. Not easy to flush. The pieces will not go backwards through the system and come out.
Also, you need to pressure check the headers on a regular basis. The early design headers are weak at the collector and the welds crack and cause water to be sucked in the bottom two tubes and in to the combustion chamber of the 8 and 10 cylinders or the 7 and 9. This causes the engine to hydraulic and parts broke. Happend to me and I had to fix a head (four valves and weld up) and replace two pistons and resleeve a cylinder!! Not a easy fix.
Just some helpful info on the Viper Engine.
Just for thought- I have 600hrs on both my engines with the stock rods crank and pistons. Clearences are still perfect!!! These motors are awesome.
