FunFlatsFishing Posted July 2, 2017 Report Share Posted July 2, 2017 I successfully ran my Pathfinder with a 2006 Yamaha F150 well in excess of 100 miles over the last 3 days without any issues except for one on day two. While in the middle of Boca Grande pass while backing off the throttle after a 15 mile run the engine alarm went off and throttled back the engine automatically. My engine temp gauge looked normal and my water pressure gauge seemed to be normal. Anyways I just turned off the engine and restarted it and the issue went away and I successfully ran the boat for the remainder of my trip without any issues. Any ideas on what happened? Maybe a clog in the water pump that passed? I had my 100 hour service 2 weeks ago. Outside of that one mishap, the boat ran perfectly fine.

dabear Posted July 2, 2017 Report Share Posted July 2, 2017 The engine overheat alert should drop rpm to about 2000 rpm it should sound a alert and if you have the round Yamaha digital tach/ multi meter it should blink in the left lower corner . You will get the same alarm deal a buzzer comes on rpm drop and the oil pressure alert should blink. The oil indicator should be in the lower center part of your tach , if you ever hear a buzzer again look at your tach and see if you have a blinking warning lamp left lower should be Heat center lower should be oil,as soon as you see what warning lamp is on shut it down. You may of just picked up some trash and clogged our cooling inlet . Hope this helps Joe R Link to comment Share on other sites More sharing options...
FunFlatsFishing Posted July 2, 2017 Author Report Share Posted July 2, 2017 I tried to look for the blinking bars but with an outgoing tide in the pass and boats all around me I immediately shut off the engine before I could really look to see what the issue is. Luckily the issue was a one time thing and went away but I'll keep an eye out. Link to comment Share on other sites More sharing options...
polliwog Posted July 2, 2017 Report Share Posted July 2, 2017 I had this happen 4 or 5 yrs ago. stopped restarted and alarm went away and stayed away. I think I picked you some junk on the water pick up that fell off when I stopped. Never happened again. I would say as long as everything else checks out it should be ok,BUT if happens again get it checked out. Link to comment Share on other sites More sharing options...
hurricane Posted July 2, 2017 Report Share Posted July 2, 2017 Grass or something on the lower. Was there floating grass around? Link to comment Share on other sites More sharing options...
FunFlatsFishing Posted July 2, 2017 Author Report Share Posted July 2, 2017 Yes. It was caught up in the tide like a small weed line. Link to comment Share on other sites More sharing options...
Miss Jazzy Posted July 3, 2017 Report Share Posted July 3, 2017 Grass. It happens to me a lot. Floating grass around here has been a big problem this year. For some reason this Pathfinder catches it worse than any other I've owned. I keep one eye on the water pressure and one on the water. When it takes a sudden drop I go to neutral then reverse to clear the grsss. Link to comment Share on other sites More sharing options...
