Long time boater - New to small engines. Few questions.

[JerEazy]

in advance: love this site. I’ve lurked for a long time. Constantly reviewing old posts. But where I am in a new spot.

always having at LEAST a 90hp engine. We now live a happy walking distance from a local reservoir and river. As such I came across a GREAT deal on a 15’ fiberglass boat (pointed bow; so not sure if it classified as a Jon Boat- but anyway). with a 98 Merc 9.9 2-stroke pull start tiller.

Was able to spin it out today and got a real nice 18 mph. Not sure of the RPMs and it’ll take a while to get used to manual tilt. But, the family loved it. And so do I.

anyway. Here’s the questions. I’m almost 100% certain I’ll need a battery in that thing somewhere in order to install now and stern lights. And assuming I’ll wire off of that battery for a bilge pump.

So so my question really is what the eff to I wire from the engine to the battery to keep it charged as I puddle around? Under the cowl of this little engine spooks me out more than tearing apart a V-6. (Maybe because the wife gave me a spending limit on this toy).

thank you in advance!

This should be what you need. Verify with Iboats staff with your motors serial before ordering. https://www.iboats.com/shop/mercury-charge-kt-battery.html

keep in mind, it will output 6A at WOT

if your motor doesn't have a charging stator, you don't wire anything to it.

your choice of stators are non, a small light stator or a battery charging one (electric start models)

verify your serial number has a charge stator or simply use a battery charger to keep the battery topped off.

Doesn’t look like I have the charging version. I was hoping to keep a small battery out of view charged by the motor. Maybe I’ll do that and just keep a charging dongle where I can get at it. At least for now.

thanks guys

did some more searching on my serial number and it's saying i have the 9.9 MH/ALT - (not sure what the "ALT" means)

i looked under the cowl and i don't have a regulator in there. flipped through the parts diagrams and it almost looks like that would be all i need. I'll call the iBoats guys and see if it's that simple (it never is) thanks again

If under flywheel you see 2 black cable packs coming down, one is a 3 wire (usually) alternator coil output to hook up a battery charger, if so, check if a rectifier is provided in the mentioned battery kit.

Happy Boating
