Ok here is a problem I have been having. I have a starting problem. :/At times I can let the boat sit for weeks and the motor will fire right over at the house. dNow when I take it to the harbor to go fishing about a half hour later it will not fire over without being jumped. :devil: Once it is started I can fire it up all day long and not have a problem.8) When I am done fishing I put it back on the trailer and head home and flush the motor and fires right over no problem. 8) I turn off the battery switches when I am finished. Next day it fires over right away at home,d When I take it to the harbor the next day it won't fire unless its jumped again.:/ Go figure? I am very anal about maintenance on my boatd. Batteries are clean and up to par on the water level. I even up sized the battey cables to get as much power as I can to start the engine. Now as I understand the computer needs to put out 40 volts for the motor to fire over. Why will it start sometimes fine and other times need a jump? I can't be the only person who has had this problem. Help!
