18' with 150
I am having trouble getting on plane with full livewell and two people in the boat. Someone has to sit up front in order to plane off. Will a jackplate solve this problem?

Something's wrong brother. I have a 189TRX with a 150FS and it planes just fine full of water and 2 280 lb bigguns in the seats.
Need more info. Motor, prop , rpm when coming out of the hole. With some props the hole shot can be tuned. Need around 3500 rpm on hole shot

Hard to say with such little info. Do you have plugs in the prop? Took my boat a while to plane out on its maiden voyage. I had no plugs in the prop then and was told if I put plugs in it would make it worse. But, I put medium plugs in all 3 holes and now it jumps right on top of the water with hardly any bow rise.
I have a merc 150 four stroke..plugs in
21 p four bladed prop

Try removing one plug and then another until the rpm reaches 3500 on holeshot.

Four stroke should have all holes plugged. What 4 blade prop do you have? Put a 6" plate on it so you can adjust the prop to pad height properly.

Could it be the four stoke doesn't have enough power??
Do you have the weed ring installed with that trophy?Originally Posted by bnick
Are your RPM's high for holeshot and feels like the prop is spinning real fast to get up on pad (blowout)?
No weed ring..
Still have to check rpms next time out
A 150 four stroke that is running without a mechanical problem should get your boat up fine.
Then it could be my boat..maybe there is just not enough weight to counter balance the loaded back
In my opinion it's your prop, that is holeshot headach.
What is your wide open throttle RPM's? That 150 has to be turning that 21p to the limiter at WOT on an 18 foot boat.
Second with no weed ring on that Trophy, I bet your blowing out at holeshot.
I would get rid of that trophy and contact triton or ask others on here what there using.
With a 4stroke you don't need really need any venting of the prop (PVS) as they generate torque pretty much through the RPM range. 2strokes do not until upper RPM range , thus the reason for controlled ventilation (PVS) to get RPMs up into the powerband.
I believe a different prop and P2P adjustment will fix it.(as long as no engine problems)

I had a trophy and without a weed ring/exhaust ring, my boat would hardly plane out. But had good top end rpm and speed but not what I thought it should be.
Added exhaust ring and what a difference in holeshot, speed stayed the same.
Changed to a tempest plus and never looked back. Better holeshot and gained on the top end.

It could be a prop like some have mentioned but has this been a resent development, meaning have you experienced this the whole time you've owned the boat or has this just started becoming a problem? I ask because I'm leaning toward a cylinder issue. Have you had your compression checked lately? I had a TR186 w/150xr6 that suddenly had this same problem and would still get up to 40-50mph on plane (instead of 60-62) with one cylinder down but struggled to get on plane. May be worth having checked to insure you aren't causing more damage. Ps. If it is compression, be prepared for a hefty bill.
