Gorgeous! She looks to be well-cared for. If you are so inclined, more photos?

For reference Stillwater is powered by a JD 6068T (6.8l/225HP) with a 2.93:1 ratio and turns a 34" prop. No stalling of course.

Oh and I love the look of her to be sure! Very similar design of hull to mine (except the steel!.)

Is she a Sutton shipyard build?

That sure looks like a DD 671 powered trawler to me.

Post the entire oil analysis. Ski can give you some pointers.

A new Cummins 6C reman will cost at least $30,000 with transmission. You will benefit from better fuel consumption (18-19 hp/gph vs 16), less noise, no oil leaks and a new engine warranty. Is that worth it to you?

You can use tractor, construction or over the road diesel and assuming you currently have keel cooling and dry stack exhaust you can probably cobble together something for 1/3 of the above. It will not have a water cooled exhaust manifold however. That is a big negative for me, but lots of others say they are fine.

If the current 671 is really trashed, I think I would go that route.

No she is in Astoria oregon

Obie 02-20-2017 12:25 PM

I am so exited about this girl. I just found her 3 days before I was leaving town for 10 days to mexico, so i have had very little time with her so fare. It had to be a quick cash deal, no waiting. But she has a good ultrasound Servay of the hull, all the little pits were welded up, and she was striped to white metal and painted. Hull is great! The feast? But what a great platform. She has 5 water tight compartments, plenty of fuel. Water tankes are 2 450 gallon, total 900. I want to cut them out and install 2 200 gallon SS.

Obie 02-20-2017 12:31 PM

TF, ok trawler forum, got it! I want to find that thread. Poor guy, had his dream then heart atack at 62, not OK.
Go now don't wait!

Sailor of Fortune 02-20-2017 12:33 PM

Why would you consider cutting out the original tanks and SS is hardly an ideal material for fuel tanks. As long as the originals have cleanout/inspection ports, I would stay with them.

No just for the water tanks. She has 8 fuel tankes, all with great inspection ports.

Hey Obie, she's fantastic in every way except one... those anchors! Perhaps you should ask the people here their advise on that, they are always so friendly and helpful when it comes to anchor-talk :popcorn:

Greetings,
Mr. O. IF I may suggest a method of getting to know your new girl...STOP. Make NO plans for at least 6 months. What seems like a good idea now may not be so in the future. Make no changes unless absolutely necessary. I really know what you're going through and the excitement you are experiencing. Been there, done that, three times already. I'm not trying to pee on your pancakes at all but like getting to know ANY woman/mistress, it takes time to establish and develop a good relationship.
When you get back on her, find a comfortable place, a comfortable seat, put on some good music (keep it low key...You know you always drive faster when a fast tune is on the radio? Don't want that. Not right now) and chill. For the moment, just forget about changing her. Enjoy her vibes and relax...

You are such a ship-disturber. :rofl:

Obie 02-20-2017 02:24 PM

Good advice, except she is part way into a bit of a refit. Like you I have done this a few times, more than I would cair to admit. For me it is looking at what is there and simplify, simplify, simplify. This girl has 4 electrical systems. 120 shore power, 220 from transformer, 32 volt, engine refrigeration, autopilot, inverter, and more. 12 volt depth, some lighting. She has more valves and through hulls, than any boat should. Two water systems, two hot water heaters. 1 220 volt one propane. Time to simplify.

Obie,
that's a beautiful salty boat, congratulations on your purchase! You probably know hull speed for that waterline should be right at 9 kts. A repower should likely be a choice of minimum horsepower needed to comfortably move your tonnage along at hull speed.
If you're going to use her a lot, i can understand why you might want to improve your GPH. good luck!

All sorts of already marinized options for coolant cooled exhaust manifolds while using a dry stack setup. Certainly not from an over the road truck though, just have to find a marinization setup kit, which isn't always easy..

Xsbank 02-20-2017 03:53 PM

I am in the middle of refurbishing my water tanks, I cut a hole in the deck and installed a hatch and I'm busy scrubbing, scrubbing and intend some sterilizing chemical and some more scrubbing. Your water tanks may be recoverable and are probably part of the hull anyway...

Gorgeous boat. If you have to repower will you do it through the side of the hull?
