What is wrong with my boat?

jeffk · 05-04-2018, 05:40 PM

Just did a quick look online and the first may be a water pressure gauge for the cooling system. Supposedly it is common to vary in pressure from very low at low engine speed to 25 or so at WOT. Different engines handle it differently. Yamaha engines hold around 11. Why do you think it is "off". Does it read differently than it has in the past?

I don't have any experience but the article says basically, see what is normal for your boat and if it changes, check it out.

What kind of motor do you have? Outboard, inboard/outboard, 2 stroke, or 4 stroke? Hard to advise not knowing. First gauge looks to me like a water temp gauge, and running hot. The other one is definitely your battery voltage gauge, and is definitely over charging according to the gauge. Could be voltage regulator, battery, alternator, or maybe the gauge itself is junk... I would not take the chance of running it till you get them checked out. The water temp is critical. You could cause significant damage if it overheats, and a relatively easy fix could get a lot worse ($$) if you run it hot...

1994 200 hp 2 stroke Evinrude Ocean Pro outboard. I recall the voltage gauge being around 13-14 and the water pressure gauge being in the middle around 10-11.

They go down when I slow down and stop.

Thanks.. sorry for lack of info

Father had the same era Evinrude back in the day. On the water pressure, it was usually around 5 or so psi at idle and around 20 or a little bit more psi at wide open throttle so I would think you are fine. On the voltage, 16 is pushing it. Probably want to have the regulator and battery checked.

Definitely overcharging IG. Get it looked at as soon as you can or you’ll risk ruining your battery.
