Location: Hayward, WI | I have Nick's old 1760GT (great rig). One of the props included is a 16 pitch Silverado Stainless (3 blade) prop. With just me and a light load the boat will do over 36 MPH, and cruises at 26-28 nicely. I can't trim up a lot without the prop starting to throw water slightly and over-rev. The 75 Yamaha is mounted one hole up from the lowest position. Would dropping it to the lowest hole possibly give me more trim range?
I often find myself with the motor trimmed all the way down in anything over a moderate chop to keep the bow from bouncing. In smooth water, I only lose about 1 MPH with the motor trimmed all the way down compared to it trimmed out as far as I can. I could pretty much always run this boat with it trimmed all the way in and not really notice anything out of the ordinary. Other boats I've owned would plow water trimmed all the way in.
There's no way to know without trying, but I am wondering if dropping the motor down the last hole might be worth a try. The cavitation plate is currently above the waterline even when trimmed all the way in.
Also have a 4 blade 15P stainless that I think gives me more trim range but I haven't run it in a while so I don't remember the details. Better hole shot but significantly slower crusing speed than the 3 blade.
The dimensions on paper of the 1760 show it to only be 2" wider and about a foot longer than my old Alumacraft Navigator 165, but in reality the interior space is much, much bigger. Looking at Nick's 1890 GT - there is some serious interior space in that boat. The glass hull beats aluminum in every way so far, in my opinion.
