Most of the TRS's were set up at 18" but they are 2" taller than a std bravo so it becomes similar to a bravo at 16" however the TRS prop is further back away from the transom kind of like a short setback as compared to a bravo. I would think that 19" for Mirage type 3 blades and 20" for 4 or 5 blades would be good with the TRS and you would be able to maintain some hatch clearance for a carb motor arrestor etc... Remember TRS spacers are no where near as easy as putting a spacer in a Bravo so you really only want to cut it once and get it right. A real 420 TRS at 19" with a labbed mirage plus should do 70 easy at sea level

Yea i will call jo and nopper on monday. i have to figure this out by tuesday b/c the glass will be done probably by wensday and i have to let the glass guy know whether or not to fill the fiberglass in.


Is there anyway to find out what my current X is without having a TRS transom jig? ppl have measurements for bravo from the bottom of the keel to the bottom of the gimbal (transom assy??) but i cant find a measurement like that for TRS anywhere... i guess i have to find a jig

Just measure from the bottom to the hinge pins. Mikes pantera is at 17.5" if I'm remembering correctly

i can probably have a measurement on a trs boat from the gimble to the bottom for you tomorrow. there is one in the pole barn sitting next to my top gun.

Subscribed for updates. Our Excalibur with a LH Konrad, a five-blade Hydromotive and a 525 SC is a terrible running POS. We were thinking of swapping on a TRS to see what happened.

What power ^^^^????

Does the Konrad act like a shorty? Maybe prop is too high

It's a 525 SC. I think it's stock, but there's no way to know. I think the prop might be too high. I'll try to measure the X the next time I'm at the shop where the boat is stored. Sparky, we may see you out there next season. We boat out of Falmouth.

The Konrad is just shy of 2" shorter iirc. With that power why the left hand drive and 5 blade prop?

The left hand is supposed to counteract the rotation of the motor so the boat doesnt lean over at speed, i think thats the idea?
