Re: Stus-List 3GMF knocking sound

One other option for a diesel tach: https://www.tinytach.com/diesel-tinytach These can be had on Amazon for under $60.00. I just built one into a new engine control panel I made for my LF38; I’ve never had either a tach or gauges on the boat, as it

Stus-List 3GMF knocking sound

Hi Kevin, The only way I know of is to use another tach... That doesn't have to be expensive or complicated. I used my R/C airplanes optical tach to validate mine and it worked fine. You paint a sliver or white stripe on the shaft / shine a flashlight on it / point the tach at it. They are

Re: Stus-List 3GMf Knocking Sound

I had a problem with a previous boat, engine dying at higher rpm's. Turned out that there was a filter on the fuel take-up, in the tank, that was partially clogged. Once I cleaned it, the problem went away. With my present boat with a 3GMf engine, I had a problem with the transmission not fully

Re: Stus-List 3GMF knocking sound

Good points Francois, I have meant to take a good look at the prop and probably do need to send it off for reconditioning. I know the bottom is a little dirty and so is the prop. But even when everything was freshly painted I still had this issue. It starts up very easily which makes me think

Stus-List 3GMF knocking sound

Hi Kevin, In addition to making sure the transmission is fully engaged (We had that issue too, for me, it was solved with a simple cable adjustment), it sounds like you should jump in the water and take a good look at your prop. What you need to do is grab the blades and wiggle them against the

Re: Stus-List 3GMF knocking sound

Yea I did that today and started it up and it sounded fine. However I didn't put it in gear or take it out of the slip. The racor was full and I didn't see any water in it either. Now it does vibrate pretty good under operation. I looked at the engine mounts though and none seemed to be cracked

Re: Stus-List 3GMF knocking sound

Kevin, Fill the fuel tank with 6 to 10 gallons of fresh fuel, try it out, and get back to us. Check your racor filter for air. Low fuel/air in the line/water in the line can all cause rough operation. These Yanmars have a lot of backlash in the engine and when you get rough operations the

Stus-List 3GMF knocking sound

Hey Everyone, Well we were lucky enough to be able to take out our 34 this past Wednesday for the Blue Angels show in Annapolis. On our way back our Yanmar 3GMF would occasionally make a knocking sound. I'm hoping you guys might know what could have caused it. When it happened: * We were about
