I'm the kind of guy who continuously does checks when under way, be it sail or motoring. I pride myself in making sure my boat is RIGHT while away from the dock. My advice to folks is to never leave the dock if you know something is wrong with the boat, as the sea will find it at the worst possible time.

Well I went out sailing this past Thursday with a friend of mine Frank.
Usually when motoring, I set the autopilot and do my customary visual check on the engine & bilge. Well, on this day, I overlooked this routine as I was having a good time up on deck. That was my mistake.

I motored into the gulf and headed south until 3:00PM. The winds started clocking from the southeast to out of the north and gusted up to about 20-25 kts. What had been flat seas until now quickly built to four footers. Not a big deal however, but I needed to douse the head sail and flatten the main for a straight line trip back.

I remembered to do my routine check of engine & bilge and this probably saved my engine.

I first looked in the bilge and saw what looked like oil & water mixed. I checked the rear engine door to look at my PSS shaft seal and saw alot of oil on my stringer and surrounding area, WTF?

I quickly pulled cushion & top panels off to see where the oil was coming from and after a few minutes discovered it was at my fuel filter.

I use Amsoil synthetic diesel oil for the engine and it was last changed about a year ago. With the synthetic, I get a year or more use than with regular oil. I do my own oil changes and always recheck the tightness of the filter three times over the next month to insure the fit.

Working below in those seas & wind, I got a complete turn on the filter before the leaking stopped, again WTF? After a year the filter decided to loosen, I never heard of this happening.

In the end, & after today's cleanup project, I found I had lost 1/2 of my oil, about 1.75 qts. and for the two hour motor back to John's Pass, had sloshed the oil/water mix all over the engine compartment & bilge. What a f***'n mess. I never before had an oil filter come loose, but now, this was a first.

JUST A WORD OF CAUTION GUYS,
always check your bilge & motor while underway, and periodically check that your filter is on tight. I'm still quite mad at myself for not doing my routine checks on the way out as I normally do. The one time I didn't, and it could've been a costly mistake.

Great report, glad you're safe and the engine remains whole.

We have a topic in our Critical Upgrades page called: "Check your engine when running - regularly" or something like that.

Good idea.

Good advice Ron, I'm as paranoid... err... thorough as you are too and I think it pays off eventually.

Not to take away from your point but I seem to remember a whole debate about not switching to synthetic oil because of the age of our engines? I can't remember though, you may have a more modern engine in your boat?

Sounds like you have been using it without any issues though?

Take care, DanM.

Ron you mentioned synthetic oil, do you think that was a factor in this in anyway, was it just a point of reference to to checking filter tightness?

My old A4 had no filter, so this is a very good reminder-- thank you and good to see that a mess was the worst issue.

Guys,

Thanks for the replies. I did check with the (newely purchased) engine manufacturer out of Miami (RB Goves, Westerbeke) and they gave me the OK 3 years ago to go with the synthetic oil for my 3M20a Universal basd on my mileage.

I wish I had an explanation for my problem but who knows. My mom has had medical problems the past four minths and I have only used the boat twice. With winter temperature changes here in Florida, I feel that may have been the culprit. You guys that haul out over the winter ALSO should take note.

Dan, I liked your reply and thought it was insightful. Brad, your concerns were relevant but I feel synthethic oil was not the culprit, it was temperature, humidity & lack of routine checks.

Funny, as I spoke with some learned guys and they were puzzled too,after a year????.

Oh well, you know what they say about the prudent navigator, you need to be smarter than the average bear........

It's all clean now, and only the oil change is scheduled for tomorrow as I have no confidence in the installed filter.

In hindsight, stay vigilant guys, and keep spare fuel filters and extra oi /filters as you never know, and the sea will find it!l.............

Ron, Congrats on dodging a bullet. I've been playing with engines of one sort or another my whole life and have never heard of a filter coming loose after a year.

I think maybe you have to make a sacrifice of rum to Poseidon and ask him to cleanse your boat of gremlins -- seems you've got one with a filter wrench!

Hey....I had that guy on my boat before. He is a b*stard!

That is a scary ordeal and I am glad that the outcome was nothing more than a lot of back breaking labor to fix the problem. I am really glad that your engine survived it. This gives me one more thing to look at!

You know Ron it must be fate, because I was down at my boat today changing the oil and doing some maintenance before the 1st spring sail. My filter was the direct opposite. I could barely get that thing off to save my life! It took two different wrenches to find one that would fit, and the bloody opening of the access door is so small that I had to take it off the hinges. To top it off my P.O.left me some "spare" filters, but the f!@#$ing things didn't even fit! Thanks a lot man. When you've got oil all over your hands from a weak pump & then have to run down to the auto parts store it kinda bites. But I got the job done. But now I found a leak on the water pump. No good deed goes unpunished. Sometimes I feel that I get into more trouble with preventative maintenance, then with stuff just breaking from neglect! lol.
