Put new gauges in this spring and added a voltmeter. It reads 14-15 volts at 3000+ rpm.
Is that right for a 225 SM?

SM is sportmaster, but that does no good for charging. Prolly PM with SM.What's a SM? On my 150PM, it was 17+ volts when I got it, replaced the regulators and it ran 13.9-14.2 on the digital readout on my Humminbird, but the gauge was in the 14-15 range by the needle, so it sounds like you're working just great!
