Greetings to All,<br /><br /> New to the forums, so I will get right to it. I own a 16.5 Ft bass boat with an 1984 Evinrude 115hp v4 w/vro (but bypassed).<br /><br />Problem 1:<br />When I purchased the boat, all the gauges were original, and not working, so I proceeded to replace all gauges, ie
tach, trim, fuel, volts, etc.), originally the only operating gauge was the tach, but it would work intermitently during trips out on the river, so I replaced it and the new tach does the same but to a lesser degree, (Bugs me)...<br /><br />Problem 2:<br />I replaced the volts gauge, and started noticing that while the engine runs, the voltage readings were swinging up & down, from 12.0 to 17.5 Volts, after a while settling on 13.4 volts, this is confirmed on my GPS Mapper, which displays voltage as well, I thinking bad voltage regulator...<br /><br />Problem 3:<br />While running the boat, some days, I can reach WOT of 5500 RPMS, (easily & what I consider normal operation), other days, I have have to work to get the engine to reach 4800 RPMS, Also while running, the engine seems to surge while cruising, 4000 rpm, then 4200 rpm for 2-3 seconds, then back down to 4000rpm, this happening intermitently...<br /><br /><br />All three problems from what I have researched on this forum, points to the rectifier/regulator not working properly, and volts & tach problem seem to reflect this, my question is if the rectifier/regulator is acting up, would it affect the ignition system and my loss of rpm's?<br /><br />Any feedback on this topic would be helpful, <br /><br />Thanks in advance for any help<br />Astroglass Ted
