Hi. while I have trolled this site for quite sometime this is my first post so please go easy! :redface:
I purchased a 1994 20' Sunbrid Corsair Bowrider with a 4.3L OMC. Soon realized this required a complete new deck, transom and stringers. i have finally got the boat back together and ready to use.... Finally. it has been a 2 year project.
I launched the boat approx 1 week ago. started on first turn of the key. ran it for approx. 1 hour to make sure all systems were good etc...
Tried to launch this past weekend. Again started with one turn of key. Idled at dock for approx. 2 min. When I shifted into forward the engine died. I could not get it started again.
Took the boat home, hooked up the charger/tester. Tested at 15% full charge and 10.5V. Charged battery, installed mufflers and started the engine no problem.
in the 2 years since I rebuilt the boat the battery (a 12V, deep cycle battery) was on charge once every 6-8 weeks.
The only thing that has changed between the 1st launch and successful run approx. 1-2 weeks ago and this weekend is the installation of a new stereo.
Here are the questions:
1. Why would the boat stop, after shifting into foward? Is this a separate issue from a low battery? The boat was already started and running/ideling fine.
2. It appears the old stereo was simply wired directly to the fuse panel, not via ignition. The old stereo did have a distinct on-off. the new stereo was wired the same way but there is always some power to it, even when the key is not in the ignition. is this enough to drain the battery between uses? Shouls it be wired to the ignition or to another unused switch (i.e. wipers)
I am willing to accept that the battery may be old and simply in need of replacement. purchased in 2008.
I charged the battery to 100%, 13.4V. After 2 hours the values were the same, whether connected to the boat or not. After 14 hours, connected to the boat, the readings were 95%, 12.4V
thanks in advance
