Contender issues

Gringo · 06-18-2009, 10:47 AM

I was down on the boat yesterday, doing some stuff that needs doing. Like, installing a swim ladder, removing the salt water washdown pump to see if I can fix it, removing the outriggers cause we never use them and there's no sense letting them sit out exposed to the sun, salt etc.

Oh, and putting a new set of plugs in the HPDI. It started running rough about three hours ago on the clock. I had taken out the plugs and the lowest one was pretty fouled. I keep a small wire brush on board and cleaned the bottom four plugs up, and it ran better. For about two hours, then it got rough again.

I dunno, do you guys think this qualifies as a fouled plug?

this is the lower plug, the one I wire brushed and re-gapped about three running hours ago. I put all new plugs in yesterday, and otherwise the Yammie looks pretty good:

Ever feel like sometimes you don't have enough hands for some of these jobs? Gotta play monkey and get the feet involved:

Hey, it works.

I just this morning got the pump hooked up to 12 volts here at the house, and it's toast. Shurflo 3.5 gpm...and I know it's gonna cost me the equivalent of the GNP of a small african nation to buy one here. Sigh.

But we need that washdown. Conch guts, two stroke oil, fish blood....there's lots of reasons.

ok, fist check all the fuel filters for water, looks like you may have some water in the fuel...

As for the Shurflo pump, replace it with a jabco and that should take care of things and give you more GPH, it is a better pump...

Actually , the HPDI's had issues with the oil injection causing the motors to foul up the plugs, I had it happen on a pair of 250's with 25hrs on them , I fouled every plug while trolling the canyon. Make sure those motors had the update done to them

Doesnt foul the top plugs, just mostly the bottom two, with somewhat less fouling on the middle two.

It's an '06 motor. Built with the mods already designed in, I think.

I had the same problem on a 200 hpdi in 2005. It turned out to be a bad head gasket. It also took the o2 sensor out.
