Have a mid or late 70s Evinrude 85 on my 16' King Fisher with an OMC jackplate/trim setup.
When the boat gets on plane, I can hit 41mph on GPS at 4600-4800 rpm.
Sometimes it feels like it takes forever to get the nose down and the boat on plane. I usually start with the trim fairly high and slowly bring it down, let the bow bounce once or twice and tap the trim down a touch and she will scream across the lake. Am I taking off wrong? I have no trim gauge.
Also, I've been told 4800-5500 is the ideal rpm range. I don't want to be near 5500 but Im not opposed to getting it up over 5000 for a little extra fun factor. Is this a prop issue?
I also feel like the motor is too heavy for my KingFisher. When the boat is attempting to take off, the bow soars up in the air and takes in a ton of water over the hull (bilge will pump out a gallon or two easily I'd guess) would it help to find a way to move my dual Optima batteries up to the bow some how? I've never been able to verify where the cavitation plate sits with the bottom of the boat either, the boat/trailer sit very low on the ground and I can't set the motor parallel on land to verify. The waters I fish are murky and it's not possible to check out there either.
Should also mention I'm 220lb and my fishing buddy is 325 so we are putting well over 500 lbs right there at the back of the boat, I'm sure that is not helping?
Last year I had a lot of starting issues, battery issues and more. I took everyone's advice from here and as far as that goes, all of those problems have been solved and the boat has finally been reliable and a pleasure to use.
I do have one more issue with using reverse. If the prop gets loaded with weeds and I try to spit them off with reverse, the motor will not go beyond 1800-2000rpms . Is this normal?
