Two questions regarding my new Starliner

Hey All,

Couple of questions...I just purchased a new 21' Starliner with a 225 HP Yamaha outboard.

#1. Anyone know how much the Starliner and motor weighs (approx)?

#2. What benefit is realized from the jack plate that is installed on the boat?

Thanks everyone!

Hi there, according to a 93 brochure the Starliner weighs approx. 1400 lbs.

Strictly a guess on the motor, I"m thinking 450 - 500 lbs.

About the jackplate - the idea is to raise the motor higher which in turn will create less drag on the lower unit which will increase top speed. The trick is to make sure you have enough water pressure to suffeciently cool the engine. The other piece is getting that balance where you don't lose the low end torque to get the boat on plane. Lots of variables to find that sweet spot - 3 or 4 bladed props, people in the boat etc. etc.

I am sure others can explain it better but in a nutshell I think you get the idea.

Another part of the balancing act is that if you bring the motor too high up, the bow of the boat will come down some and end up slowing you down. I just bought my Starliner about a month ago but in the few trips I got to take I could notice it when I brought the motor too high. The boat would go from feeling light as if it was flying over the water with the bow pretty high up, to feeling a little heavy, harder to steer, and the bow coming down a bit. The prop you are using will also affect the attitude of the boat in the water as far as bow and/or stern lift.

Jack plate

Any problems with water circulation/supply to your water pump when it is riding high?

Thanks,

Another effect that setting your engine back with a jackplate and maybe a "little" off set braket, is you create more leverage and be able to "fly" or carry greater weight at speed.
When I introduced a 10in offset bracket between the transom and jackplate on my starflite. I didn't gain a ton more speed maybe 1 or 2 mph but with the leavage gained I am able to carry 4 people to 70mph. About 5 mph's faster then without it.
Being a bow rider that leverage might come in handy, but I advise against 10'' setback maybe 5'' at the most.

Besides the obvious gains in speed by lifting your lower out of the water,Theres a savings in fuel too! The differance I noticed between gliding on the water mota down vs. mota up is over double in length, you can feel the less drag on the boat.

As for the water pressure have gage and theres plenty of opitions to try !

good luck merc245:thumb:
