Random Quote: The man who said: "Take a long walk off a short pier" Forgot to check his dock lines!
did about 50 miles yesterday, ran flawlessly. Ran 3700 RPM for about the first ten miles, then we trolled for hours at 1300 RPM, then home again at betwee 4500 and 5300. No hiccups, no overheat. Guess I got the water pump installed correctly.
For you other HPDI owners....I am really paying attention to fuel now. I pour it into the tank through a racor filter/funnel for starters. I checked the drain/sediment bowls on the two Racor filters between the tank and the motor yesterday before we left. The 2 micron one was clean and clear gasoline. The first one, the 10 micron one, had maybe a third of a thimble of dirty water in it. I don't know how many milliliters that might be. Not much. About three good sneezes worth.
Then I checked the racor filter/funnel, which is, I believe, 27 micron. and it had maybe a shot glass of water in it. That came from 10 gallons of fresh fuel bought a half hour before from a Texaco station. So, it seem no matter where I get fuel here, it's got water and dirt in it.
Hey, it's a pain ( especially when paying $ 4.30 a gallon for it) but with that knowledge things don't seem so bad. It's an identified issue, and one easy enough to control. Sixty bucks worth of filters before the outboard sees any of it.
I wonder how many of the "bad" HPDI stories we have all heard could have been traced back to contaminated fuel...
I doubt you had that much contamination in 10 gallons of fuel especially after you did all the filtering. I think most of it is already in the tank, especially the water. You probably do not keep the tank topped off therefore the natural temperature changes during the course of the day will suck moist air in as the tank vapors cool/contract at night. Plus you probably have junk in the tank from lack of use.
Put a 1/4 gallon of gas in a one gallon jar with a small hole in the top, set it outside in the sun, inside of a box of some sort to imitate a tank in a boat in the sun. Just a thought to simulate a tank 1/4 full.The see how much water vapor is sucked in.
Maybe use the the tank on your boat with the size best suited to your most common fuel requirements? For example if you have a 100 gallon tank keep it mostly topped up and run from it. I bet the junky stuff will decrease over time but never go completely away.
I don't think thats a good idea. The tank is 180 gallons. If I kept it topped off, I would have all that fuel sitting there evaporating the good stuff, and concentrating the gunk. We don't get big temperature or humidity variations here. Daytime temps vs nightime, theres less than ten deg. diff.
I am going the other way. I just buy enough fuel to have what we need for the day plus a comfortable margin.
Easier to filter it than to drive around with hundreds of dollars (and pounds) of old gasoline.
hey, what kind of pictures can I show you? A 300 HPDI running like a well-oiled machine? Finally?
Here we are scooting out toward the cut in the reef...running sweet:
The bottom here is about 12-16 ft. deep at the cut over the reef, and then it does a shallow slope down to about 200 ft, and then suddenly the bottom drops out and it keeps on going down to 5,000 ft. within a mile and a half of shore.
As you can tell from the t-shirt with sleeves, it's winter time here....
I don't know if you can tell from this, but that's the beach in the background and the Furuno is reading 1077.
We trolled for about three hours from 160 ft. out to around 800 ft. Tried skirted cedar plugs, Gatlin-jets in pink and green, skirted rubber Williamson ballyhoo....all lures that have produced in the past. NOTHING. not even a single strike.
So I cranked the tabs down once we were back on the Caicos Bank side of the island and we scooted over about three feet of water for several miles until it deepened up enough to relax
It's a high pucker factor in a deep V. You HAVE to keep it on plane, and you have to keep an eye out for coral heads and rocks. You dasen't daydream, or you will likely suffer some consequences...

Wow...........looks nice Gringo. But I have to say..............you kind a suck. I ran across to the mainland last night at 9pm to pick up my buddy in a 18ft BW outrage. It was a balmy 41 degree's with a slight drizzle. Hey.......it could be worse........at least it was calm.
You live in a beautiful area.........your a lucky guy.

I chatted with him about a month ago, and the engine was still running well.
If I recall, I think he is looking for something smaller, that draws less water.

heck, man, this motor runs like a top. Had it out twice last week, put another 80 miles on it. I still drain a half cup of crap out of the Racor before ever trip.

Are you having any more problems with plug fouling ?? I dont have any water intrusion
Im fouling plugs and have not figured it out yet
I was thinking of doing the decarb with sea foam

I have not had to touch that motor since I got her fixed, cleaned out, and running. I have noticed lately that I need to let it warm up a few minutes when I first start it , After it's run for about three or four minutes, it's fine. And this is only ater it's not been run for a while. After the first start up it's fine the rest of the day.
But the stuff in the Racor is mind boggling sometimes.
This was a couple weeks ago, (Apr. 4th) after running 20 gallons of local marina gas through it.
even the fuel floating on top of the dirty water was cloudy. This is from the 10 micron Racor. The fuel in the 2 micron was clear.
Nope, that was after buying 20 gallons at the marina a few days before. We took the boat twice that week. When I buy gas at the marina I don't use the filter funnel. It cannot handle the fuel pressure at the marina hose, splashes all over the place.
I use the filter when I buy gas at the local Texaco gas station, not a marina. I fill two jugs, 12 gallons, and put them on the console. I use clear tubing to siphon from the jug(s) into the fuel filler on the gunwale. That's when I use the small Racor funnel with the 127 micron filter. I don't have nearly this dirty fuel issue when I do that. Sometimes I get a little clear water out of the separator.
But driving to the automobile station, filling two jugs, driving them home and hauling them up into the boat, on the trailer, and siphoning....quite frankly it's a pain in the patoot. So I had thought that by now the fuel at the marina would have been clean, several tankloads along. And the guy at the marina swears to me that he checks his filter weekly. I dunno.
If that's true, and his filter is working...why do I get this dark stuff when I buy gas from him and not when I buy Texaco at the automobile station?
Seems to me that if the prob was sludge in my own tank I would have this issue every time I checked the Racor. I don't.
I'll check it today, just to see how it looks. I bought another 20 gallons from the marina last time we were out, and the boat ran fine. That was a week ago last Sunday. So whatever is in the racor today came in from the marina. At least, I think so.

The red looks like rusty water coming from the condensation on the inside of the marina fuel tank- the surface not covered with gas produces rust. Probably saving $$ keeping less fuel inventory in his tanks than the gas station guy who sells more.

Good point, also wonder how old the marina's tanks are?
In the USA tank regulations are strict so the tanks tend to be in better condition.
