PLEASE HELP!
I have a 2001 Triton TX-186 (dual console). It is basically the same as the TR-186, but it doesn’t have carpet and has an added baitwell in the back.
I recently replaced the Mercury XR6 150 that came with the boat with a brand new Yamaha Vmax SHO 150. The hole shot on the new Vmax SHO 150 is almost nonexistent. It really struggles just to get on plane.
I am using the 23p Tempest Plus prop that was on the Mercury with the new Vmax SHO. The Tempest has all of the large hole vent plugs installed. With the Vmax SHO, the center of the prop is sitting 4.25” below the bottom of the pad.(This seems kind of low to me)
With 3/4 tank of gas, two adults, and the livewell 1/3 full; it bogs down and barely is able to get up on plane. It takes almost a full 20 seconds for the bow to drop at WOT with the motor trimmed down all the way. When I am finally able to get the boat on plane, the prop tends to want to blowout at WOT or when making turns. I’m getting 59-60k rpms at WOT.(which seems pretty high)
I already have $16k sunk into this motor and so far it has been a huge disappointment.
I came here first because of all of the knowledgeable people on this forum. If one of you guys or gals can’t help me, then nobody can.
If anyone can give me any suggestions on how to fix this issue, it would be much appreciated.
Thanks
