J25RCSA

It had electric start added on, im confused what i actually have...no rectifier?? Does this mean theres no charge at WOT? Whats been changed under the flywheel if anything?? Im curious whats been added on besides the solenoid and the starter motor, or can someone tell me what wasnt on the motor before elec. Start was added?? J25rcsa is model# 1980

Hi,
I have the same configuration on my 25 Evinrude. If you want that 5 amp charge you need to install a different stater.
Last time i looked it was about $350.00. A well charged battery will start your motor all weekend. Just charge up and
go have FUN!

I have a similar motor (1974 25hp) it has factory electric start with no charging system.

For our 2 skiffs where the 'combo' or dual-purpose battery starts the 15hp motors and powers the auto bilge pumps, we use these. We just hard wire and water-tight all the connections (use 5200 in any connector [after connection of course], then marine adhesive-lined heatshrink over it) and keep the panel clean. Cover the leads in spiral wrap or the UV will kill them.

They have been out there in continuous saltwater-environment exposure for 2-years now and we've never lost a battery or had a power issue. Only $15 from Harbor Freight, link = https://www.harborfreight.com/15-watt-solar-battery-charger-62449.html

Yes sir it is all original except the electric start..my grandpa bought it new in 79-80 and for 95% of its running time it was on no wake lakes and the other 5% of the time was at a lake with no restriction on speed once in the spring every year after ice out to run it a bit at WOT ( to make sure everything was sound) and one week to ten days every summer when we would go to south dakota... He took very good care of it as have i since 2004 when the boat and motor was given to me.....

So do i have a different stator under the flywheel or no stator and just coils???

Yeah im not worried about charging at all...i usually charge the battery about every two weeks and only had it not start once since ive had it and all it took was one pull and it fired right up...i was just curious what excatly what i had because the absence of the rectifier and the black terminal deal that has all those wires connected.. I guess i assumed any electric start would have the charging capabilities....just out of curiosity are the flywheels the same with mine and a motor that has the stator, rectifier etc..? And is there anything under the flywheel that would be a good idea to replace because of age or is it one of those deals if it runs fine dont worry about it until it doesent run fine? Haha.. Sorry about all the questions but why does the 25 and 35 have different gear ratios when for the most part besides the couple parts on the exhaust housing and the swivel bracket and lower and carb they are the same engine? Or did i just answer my own question?? Meaning the lower is different (thru hub exhaust)?

just looked....the different gears in the lower.

Thank you pappy, one more question and ill get out of your hair for a while... I have a 81 25hp evinrude that was given to me but was missing cyl head and cover, i bought them on ebay and i was wondering if i can make the head gasket( i have a roll of material)) for it or is it not a good idea since it will not have the two metal rings that seal the cylinders like the oem's and other(sierra etc..) Aftermarket gaskets have?

Paper gasket won’t cut it.

You can use copper sheet like the go-fast guys do, but at the cost of a sheet of copper your in head gasket money already.

Paper would be fine for the water jacket though.

Absolutely not! And using a copper sheet between an aluminum cylinder head and aluminum cylinder and crankcase would set up one Hell of a battery, even in some fresh water! You would have nothing left but the copper gasket in a short amount of time. We do not even recommend the use of a never seize that contains copper in it for the same reason.
There is only one way to do this and that is to purchase the proper head gasket.
In this forum we strongly encourage folks to do it one time and do it right. That includes using OEM parts where available. Again....marineengine.com is your friend. At least you can look up the part number and search Ebay for a less expensive part.

So these only deliver .125amps. Guess there is no worry on over charging without a limiter.

Would this and a rectifier give me charge capabilities? (0581730)

I remember what you said...my grandpa and i fished mostly no wake lakes...i fish the river and other lakes that are not no wake...i was just curious and will probably not do it but the stator is only 80 bucks nos so it dis cross my mind...i agree about not needing the charge as my battery will go a week or so before the starter has trouble engaging tje flywheel....
