I have just replaced my main and jib with new North sails. As the forum seems to have fallen silent (is everyone watching Wall Street instead??)I'll take the...

Hi Edward-- It all sounds so good. Our sailing season is sadly coming to an end here in the N.E.---yours is apparently in full swing for several more months??...
Just wanted to let the group know I got an unexpected surprise from Warren pandy at Catalina telling me that my glasses rack is finished. They are now trying...
Folks, I need some help. The 3JH4E Yanmar on my boat (2008 #145) is overheating. It runs near 180 degrees at engine rpms under 2600, and well over 180 on...
C387 #96 runs at 180 all day at 2500. Anything above that jacks up the temp to (I'm guessing since the gauge is ambiguous in that region) around 190 but not...
i can agree with both of your results more or less, 2,500 or more means above 180. Max RPM under load 2950(ish) Russ Monaco C387 #95 Alderu ... From: Tom...
Tom, Have you ever tried running for 10 to 15 minutes at speeds above 2800 rpm? If so, what did the temp gauge and alarm do? Jeff ... From: Tom Brantigan To:...
Russ, I need to be pretty specific before I can conclude that newer 387s have a cooling problem. Have you ever tried running for 10 to 15 minutes at speeds...
WHEN DID 180 DEGREES BECOME AN "OVERHEATING" SITUATION? Does the Yanmar manual state that that temperature is too hot? Everything that I've read and...
Jeff, This is very interesting, again. I have had this very problem since I took delivery. I have a Gori Three blade prop that I have always thought was over...
Wes, Yanmar says that ideally you should get a maximum of 3100 rpm under load, you should be able to run at 3000 for one hour or less and 2900 all day long. ...
Hi Warren, Our sailing season runs all year round......one of the blessings of a warmer climate. My boombag was made by North Sails. I also need to stuff the...

Jeff-- Don't understand your RPM #'s, unless your gauge is reading 100 RPM high and you're allowing for that. In short, Copies of Operation Manual, Service...
Warren, The specs for max rpm under load are as you state. My tach is off (under) by 50 rpm, but all the numbers that I used were corrected for that. The Mack...

Jeff- I don't know who the Max Boring tech consulted with. I can only relate that I've had several conversations with Richard Mastry, whose Mastry Engine...
Warren, The Mack Boring tech is consulting with Yanmar's regional headquarters in Buffalo Grove, IL. Among other things, he wants to ensure that he doesn't...

Jeff- The specs use the term "Fuel Stop Power" when referring to the 3000 RPM. My understanding is that the engine should not run above that speed under load....
Warren, Earlier this summer I borrowed an infrared thermometer and then I purchased one. The Yanmar tech has one too. All 3 instruments have shown that the...

Jeff- I hadn't seen those the 210 deg temp [along with the 4 instruments]--probably just missed it. Agree that's high, especially at 2750. Think you said that...
Warren, No problem. Again, I appreciate your input. He inspected the entire system. Next step is to pull the bundle (tubes) out of the heat exchanger and check...
Last season with my old fixed prop my temperature also went up at the end of the season when at higher speed (and RPM). I actually replaced the impeller, then...
There have been several discussions on this over the last few years. I think generally the heat exchangers spec'd are adequate but don't have any excess...
Jeff, I am not sure this will help, but I found it on the 320 list where they are talking about overheating too. Maybe just one more thing to look into. I have...

Joe-- Sorry about your leg. Interesting info. Doubt that antifreeze would deteriorate so quickly, especially the "Long life" type. My contacts at both Yanmar...
Jeff & Others, My 08 387 with 58.5 hours and fixed 3 blade prop tests at + or - 50 rpm thru the range. At 2600 rpm the temp is about 180. I've run at...

I own C387 #21 Ocean Dancer. I am the original owner and had overheating problems from the start. After consulting Mastery directly they recommended a ...
My boat is located north of Boston so the water temperature rarely gets up to 70 degrees F, and is more often in the 50's to 60's. Plus I was in the same...

Craig-- Makes sense, but the outside water temp also increases over most of the season, so that may also have contributed to higher engine temp. Warren ...

Mike- You should be able to reach the max loaded rpm, which is 3000. Seems like you've already been there, so your prop is not over-pitched. Temps also seem...
