I have a friend that bought a 2006 Monterey 214FS Wt 3400 pounds Has a 14 x 21 3 blade stainless prop. Apollo Brand I think.Volvo penta SX Drive. Chevy Small Block 5.0 liter with 2 bbl carb Volvo 5.0 GL.. I have a 1992 Sunbird 20ft with 5.7 OMC Cobra. My Trim gauge moves vertical, top to bottom. Underway my prop does not break the water till I am way up to almost trailer position. His gauge moves horizontal, to the right is down and it moves to the left when drive is coming up. There is no indication as to where trailering position begins. His drive is definitely going down all the way. Problem is.. it starts to throw a rooster tail and begins to slip just to the left of 3/4 by the time its between 3/4 and the 1/2 way point, the prop is almost free spinning and speed drops. Another probably unrelated issue is the tach. We are moving along about 21 MPH at 2000 RPM and increasing to 45MPH brings the tach to only 3000 RPM but sounds like to me the engine is at WOT. I've purchased a diagnostic tach and I'm gonna verify the tach next week and probably find it is wrong. It is a Faria with hour meter. Ive read that Faria Tachs have calibration screw on the back so I may try that first.. I run a 17 pitch prop on my boat and It has a crazy good pull up for heavy wakeboarders. His boat is heavier and has little smaller engine and a 21 pitch prop but seems to me it takes too long to get on plane and bow stays high all the time. I was wondering is this characteristic of this type of boat? once we get the tach straighten out I was thinking he would benefit from a lower pitch prop for pulling his kid on a tube and my fat *** on a wakeboard and possibly a 4 blade for transom lifting and in the future maybe trim tabs??
