I recently inherited a boat with a Johnson 40HP VRO motor. It's not running right; I suspect it's a simple thing but I'm at a loss right now, and figured I'd ask around.
Basic scenario: Fresh gas, connected right, pumped up (oil reservoir also). Battery charged and cranking.
When I turn the key (push it in, which I think is the choke; lift the throttle lever) it cranks, catches, revs up .. and dies after about two seconds.
If I do it again, same story .. it catches and quits, catches and quits (after a few times the battery runs down, of course).
Can anyone tell me the simple thing I've forgotten?
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.
