1775 Lund Pro V help

I have a 2004 Lund Pro V with Yamaha 115 hp, with Cabelas 13×17 SS prop. The best I can get out of it is 32 mph (GPS) in good conditions and with a light load. I found that most people get close to 40 mph with similiar set ups. What could be some of the reasons I’m not getting more speed?

I have 1775 with a 75 Yamaha and have had numerous props on recently and everyone of them has moved me between 35-40. Not to ask a dumb question, but you are trimming the motor once on plane?

Yes I am but it’s possible that I’m not doing it right. This is my first boat so I’m just learning.

I have a 96 1775 Pro V (115 HP Johnson) with a 13 X 19 SS prop. I can get between 40 and 42 mph. If I don’t trim it, it is closer to 32.

Does your boat have a trim gauge? If so when your running wide open is the pin level? You will want to go alot higher. Just keep raising the motor and it will stop by itself. You should feel a slight wiggle when the boat comes to full plane. I have a 96 Ranger Cherokee with a 115 V4 and a 13×19 ss prop and will top out at 45mph. It took me along to figure out that i was trimming the motor up high enough . Hopefully this helps, Dan

yeah, youre not trimming the motor.
I was driving a buddies boat last year and he was like “man how the he77 are you getting it to go this fast?”
he was leaving his motor trimmed all the way down.
Have it down on take off but then start raising (trim up) till the bow starts to porpuse (bounce). Then trim down (lower) till you find the happy medium with speed and no porpuse.

The Chucker is absolutely correct.
Plane, trim up til porpuse, trim down slightly until bouncing stops. If you have a trim gague, note where the needle is at this happy medium, then every time you plane out seek out that spot on the gague. One more thing, once you find this perfect spot the ride, speed and economy all improve.

Thanks everyone. My trim gauge dosn’t work so I’ll try to get it fixed this week. Then on the weekend I will try to work the trim to see if I can get it right. I will report back after that.

Sandacz, you really don’t need a trim gauge. Trim it all the way down, take off, once your up to speed trim the motor up a little, then a little more, then a little more until you feel the prop starting to slip and your speed with decrease, then go back down a fuzz. Once you find the sweet spot you’ll know. Look where the spray is coming off of the boat when at wot. It should be coming from behind you, look at the wake the boat throwing at this time, should be wide and flat.

Once you get used to the new boat, a trim gauge isn’t really needed, you can go by feel and sound.
