Hi everyone,
I'm new to the forum and looking for any advice you can provide.
I recently purchased a Sylvan L5 25'-10" tritoon with a 200hp Yamaha last year. The boat has no problem getting up on plane but seems to be lacking in top end speed. With 2 adults. no gear and a full tank of fuel(60gallons) it tops out around 25 - 27mph. This seems slow compared to other posts I've read about with other boat manufacturers.
Any input would be appreciated.
Thanks, Joe

Hi Joe,
Welcome!
What is your RPM when running wide open at that 25-27 MPH?
Did you trim up to try to lift the front of the nosecones up a bit?

Running 25-27mph Wot at 5200 Rpm and trimmed up.
Re: Sylvan tritoon speed
Check to see what your wide-open RPM should be. It seems to me that it should be closer to 5800-6000. If so, you may have too much prop which will "lug" the engine down and not reach full potential. Much depends upon the diameter and design of your pontoons and weight distribution front-to-back.
Yes, I would think that 30-35 MPH would be reasonable, but that would depend upon whether you can lift the nose cones up on the surface of the water. With my 25' two-tube boat and 115 HP, I cannot so you see my bow wake and laugh!![big grin2 :biggrin2](./images/smilies/icon_biggrin_2.gif)

Re: Sylvan tritoon speed
seems slow I can run that with my 22 Sylvan 2 log and a 115 Merc.
Re: Sylvan tritoon speed
Yes, if you're only running WOT at 5200 RPM, you've got a mismatched prop. That Yamaha should be at about 6000 +- at WOT. As a comparison, I have a Yamaha 150 on a 23' tritoon and run at 6000 WOT and can touch 40 MPH GPS speed.

Re: Sylvan tritoon speed
Probably has a stock "play pitched" prop, so customers don't beotch at dealer because they can't pull a 10 ft tube with 8 kids or 2 drunk men on it
You need to decide what you want, look at your prop and write down numbers, Halloran at propgods and tell them what you want 5o do.
Slow get up and fast cruise
OR
Pulling power
Or stay with your in-between prop.
I would get another prop and swap out depending on situation![thumbs up :thumbsup](./images/smilies/fing34.gif)
