I have a problem that's been hard to solve, thought I would ask here. I have a 17.5' Warrior Falcon (SC), mated to a Yamaha F100 four-stroke. This mating has never performed like I though it should. Gets on plane, but has very little trim adjustment before "porpoising". I know my prop is properly matched to this boat. Yamaha says the correct prop should be within 500 rpm of the upper range of rpm at full speed. Max rpm (in the owners manual) is 6000, and my boat runs approx. 5850. If i have a full load of gas (36 gallons), and an extra guy with me, I HAVE to fill the front livewell, or the boat porpoises in the fully trimmed-down position. What's up? Should I consider using a different mounting hole? If so, should I raise the mounting of the motor, or lower it? I want to hang a kicker on the back of this rig, yet I'm afraid the extra weight will make the boat a pig! Any advice would be appreciated!
I just figured that it is easy enough to just get a 3 bank so when the boat is not in use I can keep all 3 batteries charged. I have not bough a charger yet, maybe I will give it some more thought.
Edit: After thinking this over, with the size, weight, and heat output of the charger (as well as the cost) I think it makes sense to just
buy a 2 bank charger, I have a smaller charger i can use on the starting battery when the boat is sitting at home. Forgive me, for i am a retired engineer and I have to obsess over everything...
Congrats on the motor! I think you’ll like it.
I can’t say much on the charger location but I’ve seen them under the lid in back compartments and under center rod lockers. 160 degrees is more than I expected to hear.
Curious why you’re opting for a 3 bank charger with a 24V trolling motor. Unless you don’t feel you be running you big motor enough to keep that battery up as well?
I did buy an Minnkota Ulterra, thanks for the recommendations. I had a bunch of Cabela"s bucks saved up, which helped. Now i need to
get an onboard battery charger. Where do you guys mount these things in your boat? The manufacturer I am looking at {Noco genius)
says tht their 3-bank charger will run at 160 degrees, seems like a lot of heat in an enclosed compartment? Thanks for any input on this.
Wasn't terrible at a state park beach. Antelope island maybe. I wouldn't recommend it as a beach destination tho. Figured I was there, I'm getting in it.
