2006 25' Godfrey Sweetwater, 115 HP Yamaha - that's what I have. Now, the problem:
Last summer the trim gauge quit working. While it was stored over the winter, I had them fix it for this summer. The gauge now works, but I'm concerned about the accuracy. When I first lower the motor, it goes "thump" and stops - gauge shows dead center. When I run the motor in that position, at 2500 RPM or higher, the motor races (sounds like the prop is out of the water). If I lower the motor more to get to the "all the way down" position, it runs fine (unless in rough water - like leaving Aquapalooza Saturday).
I'm wondering if the boat is too long for the motor size and has to be all the way down to keep the prop from racing. I've ridden with other folks with the same motor, but shorter boat (22') and they ride all day in the middle well over 2500 RPM.
Has anyone had a similiar experience or have an answer to the problem? Should I take it back to the place I had it repaired? I originally was concerned that if the trim gauge didn't work, what about the gas gauge? Gas gauge seems fine - just that annoying trim. Got me and others I've asked about it stumped.

I have the same motor on a 24 foot pontoon. Where I trim the motor is dependent upon water conditions and the number of people on the boat. If there are a lot of lard butts on the boat and they all want to sit in the front, I have to trim the motor down as you describe, because other wise the prop cavitates.
You say "When I run the motor in that position, at 2500 RPM or higher, the motor races (sounds like the prop is out of the water)."
Is the motor continuing to run at 2500 RPM and just making a racing noise, or are the RPMs going up?
Did it act this way before the gauge went kaput?

KA - thanks for your reply. The answers to your questions: 1)yes, the motor races AND the RPMs go up - I usually ease way back on the throttle and go back up slowly to find a comfortable speed. 2) It did not do this when we bought the boat in 2009. The gauge went out mid-summer in 2010 and I just waited to have if fixed where it was stored.
I understand it's common on Yamahas to have a factory installed "collar" on the motor for the trim made of plastic. Supposedly, it's common for the plastic to break and they replace it with a metal collar. That's what supposedly happened to my gauge last summer - plastic collar broke, replaced with metal.
By the way, yes lots of folks like to ride out front and I trim way down to accomodate the added weight in front. But this past weekend (and several previous ones), it's just my wife and I and she rides under the Bimini next to me, so it's very annoying to deal with this with no weight consideration up front.
Thanks for listening.

Trim motor in or down to lower the bow of the boat. Trim motor out or up to raise the bow. In rough water the prop will come out of the water sometimes on pontoons. Always trim you motor down in the prop is racing and the boat is not gaining speed. You are cavitating the prop. The trim gauge can be adjusted so it reads all the way down and up in the trim motor position. The guage will stop moving in the tilt position once you have reached full trim up.

Here is my 2Cents.. I always bring the trim full down when ever I'm at idle. I also do this as I go into a hard turn. It's a habit that I teach for driving a boat and in my opinion it's as normal and necessary as putting a car in park when stopping. Full down is where it should be at idle speed unless water depth is a factor; it also needs to be down to grab in a turn. I really don't even look at the gauge because I can hear when it's where it needs to be. As you accelerate up to plane, now it's time to trim. Trim will depend on your load and feel along with instruments are the best way to get it correct. Watch your speed and RPM....if the speed drops and the RPM increases, you went too far. Try and get the best speed for the lowest RPM; also, if the nose starts to bounce, you will need to back it off a little for comfort. As KA said, trim will be different for variations in both load and water conditions. Good Luck with it.

The above comment you made was dead on. The original part, indeed was plastic and would break. The replacement part is metal, and kinda cheesie, simply put it's kinda NOT adjustable but you can bend it somewhat but it works. And, as someone else said, trim it down!!!!! It's time to "re-learn" your settings because the gauge is showing you different readings than before. Trust the actions of the boat NOT what you read on your gauge. I went through the exact same issue with PCAL when his boat was here. Should you want to chat about it, feel free to call me at 334-358-2838. i will explain to you where the "metal tab" is at, and how you may can get it to show you different readings.
Respectfully,
Steve
ps. The lake shop is caught up, so if you need something done asap let us know.

The lake shop is caught up?
Now you tell me - when I took "Summer Love" in earlier this year for a new starter and impeller, I dropped it off late Saturday morning, and it was probably the next Wednesday that Ronnie called to say it was ready... :-) We did finally get it out some yesterday and all is well, I guess I can accept 2 1/2 days for a job well done. Thanks Cathouse...
