So I just installed a CMC 5.5" setback manual Jackplate and ran the boat yesterday. At first glance it rode nice but noticed the cab plate being about 1.5" higher than the waterline! I guess I had it set too high at 2" even though water pressure was about 17psi steady, dropped to 15 a couple times but no less.
My boat is a 16.5 Center console which is pretty light for the size I think at 1060 lbs dry. Motor is a '95 Yam 115 V4 (2 stroke) I was doing 49mph with me an another person on board before Jackplate with a 20" laser 2. This first run was with a 19" trophy plus and it seemed the boat was riding higher on the water surface, like the stern was more "out" of the water, but when I dropped the motor 1/2" lower the cav plate was buried and the boat was porpoising really REALLY bad, like I couldn't almost control it at all unless I slowed down a lot, even coming off plane it would start jumping wildly...?!?
I couldn't even take on a wake from a cruiser hitting it directly from the side which isn't good but with the laser I felt the bow was riding wayyy higher and I could take on waves like they weren't even there yes at almost full throttle it was never a problem....
I don't know what's going now I should have raised the motor another 1/4" while I was still in the water but I pulled out as it wasn't a good day, speedo tube burst off and filled my console and wiring with water, it just wasn't good so I called it a day...
Got it home and raised it about 1/4" for next time to try it, it seems that 1/4" height adjustments raise/lower the cav plate more than 1/2" or 5/8"!! So I'm gonna try minor adjustments till it's right.
I was told the trophy would grab and bite better and hold better especially than the laser and also launch better, in fact it was worst in every single aspect??? Also my laser was "worked" from a prop shop whereas the trophy plus was brand new pretty much....
Starting to feel the trophy being more for heavier boats instead? I think the laser runs better on lighter boats but the main thing was I wanted more power out of the hole because hole shot with my laser isn't the greatest but so far much MUCH better than this trophy?
Could is be just the fact that I'm also sitting back 5.5" in the water now? Would that make the boat porpoise? I rode fine when the height was too high but I was scared of maybe it was tooooo high because I've never seen the plate run that high up before, scared of cooling problems so didn't wanna take the risk..
The hull is a V and there isn't any type of hook or anything it's fairly straight and smooth. Just looking for some help and pointers as to what to try with next? Goal is to get a little more speed as the Jackplate is supposed to help with getting higher up so more prop correct? Also forgot to mention when lowered it was pushing me 71kph as opposed to the 80 I would normally get... And I thought trophy was supposed to be faster?
