As most of you may or may not know I have been overhaulin my 21' Checkmate Starflite. Here's the setup:
1988 21' Checkmate Starflite w/ 2005 Merc 250xs 20" Torquemaster with Nosecone. 10" CMC Hyd jack plate. Motor is bolted on bottom holes to jackplate. I am running a 24p Trophy Plus. I took it out on Sunday and was running at 5600-5700 rpm around 68mph. I thought for sure I would have to go up in pitch but that does not seem to be the case. Also the boat sits a bit lower than it used to due to the weight of the new motor. I feel that the rear platforms may be dragging, so I am going to take them off and see if that makes any improvement. Also my buddy has a 23p Trophy Plus which I am going to give a try and see if I can get the rmps up a bit closer to the 6300 rpm rev limiter. I know some of you guys have similar setups ar setups with 200's running in the 70's. I thought that I should have been able to hit at least 80. Any info would be appreciated.
Thanks,
Dave
