I HAVE A 1999 FW HORIZON 220H, NEW ENGINE 5.7 VOLVO PENTA, NEW IMPELLER, YESTERDAY NOTICED ON THE WAY BACK TO THE DOCK THE TEMP GAUGE ON MY OEM AUTOMOTIVE STYLE GAUGE CLUSTER WAS READING ABOUT 3/4 UP THE GAUGE TOWARDS HOT, NO NUMBERS ON THIS GAUGE ITS MORE LIKE A FUEL GAUGE, ITS DEVIDED INTO 1/4 INCRIMENTS. JUST CHANGED THE OIL AND FILTER MERC 25/40 IS WHAT MECH. TOLD ME TO USE. All I did was put muffs over holes on drive unit, turned on garden hose, started engine, had water flowing out near the back of drive unit, and run 5 minutes then pumped out engine oil. I think the drive unit was in up position, dont know if this makes any diffrence or not. P lease and thank you all for any and all help. |

Howdy, You really should not run the engine with the drive all the way up. That or changing the oil has nothing to do with possible overheat. You won't know if the engine is overheating unless you use a known gage to determine. If you or someone else replaced the impeller, was it replaced because it was damaged from running dry? , did it completely fail?, was the engine overheating before? When the old impeller was removed, were ALL the pieces recovered? It's a 1999 model, was the oil and power steering coolers inspected for blockage from previous impeller failures? Although unlikely, the T-stat might be at fault. has it been checked? You didn't say if the boat is used primarily in salt or fresh water...... If used in salt for the last 10 years, it's very possible that the manifolds and risers are getting clogged with rust. That will reduce water flow through the system (by reducing water output thru the risers) and cause overheats. regards, Rick |

The boat was a fresh water boat, that is what the dealer told me. I have used it about 25hrs. on fresh water and the engine has a new gm block. the impeller was changed because mech. said it was a little bad. the only time the engine was run with prop all the way up was with muffs on to warm oil for a change, the temp gauge would read about 1/2 the way up the scale on gauge. I will check the things you mentioned first, before getting into any thing big. I thank you very much for your time and info. |
