'95 Sportster will not start

[kringdoo]

It was to be a beautiful day to be on the boat yesterday. I had been out the night before and it started right up. But I noticed it didn't quite get up to speed, 35 instead of the normal 45mph. I decided to grease the drive shaft, replace the plugs and check everything. Prior to starting my work I ran the engine blower, which worked fine, but I didn't start it. I did all the work above and then tried to start it, with land yard and key on, pressed the start button and nothing happened. I put it in reverse and forward n pressed the button and the normal beeps I expected didn't sound off. Back to Nuetral ... still nothing. blower and lights all fine, probably not the battery. Checked, what I think is the grounding wire, on and off and cleaned the post on top of engine... Still nothing.

Sounds electric, but where do I start? Any Ideas, please help!!??

Thanks in advance!!!
