4 Product Questions

I am looking for at thermostat for my 250hp Etec DE250PZABF. This is a 2016 model. Is this the correct thermostat for that model engine.

John

Answer:

Yes, that will be the correct one needed.

Does this thermostat come with the gasket required?

Will Rek

Answer:

The Thermostat does not come with the gasket. That would need to be purchased separate. I am showing part number 0339044

What is the difference between these and aftermarket thermostats?

Wade

Answer:

The factory thermostats are stainless steel and do not corrode like the brass ones from other places.

What degree does this thermostat open at?

Angel Lujan

Answer:

This thermostat opens at 143 degrees.

Crowley Marine Inc had every part that I ordered for my old 1969 Johnson outboard. I was surprised that there was still parts still available. I surfed the internet for parts and Crowley came up, so I checked to see if they had PayPal because that is the only way I pay on the internet. Long story short Crowley had PayPal and I have been very satisfied with all my dealings with this company.

Problem fixed: water pump required replacement.

step by step? For the most part I use trial and error, I am no expert. In this particular case I will be replacing the water pump. Other repairs and replacements are; rewiring the motor and harness, replacing the generator, and the starter, replacing's the points, condensers and the coils. I found that the smarter way was to repair what I already have instead of purchasing new and learning by purchasing the repair manual and doing the work myself, I have become a semi expert with old Johnson outboards

Problem fixed: Engine overheating

Engine was over heating, sounding a constant alarm. Tell tale still working. Engine was only very hot to the touch at top of head on one side only. Diagnosis was a thermostat wasn't opening on that side. Removed thermostat housing, although difficult to get to, it does come off without needing to cut the cowling or lifting the powerhead. A lot of old gunk in the thermostat area. Cleaned up, Replaced thermostats, refit, problem solved.

Problem fixed: Just an old motor in disrepair

Working on replacing just about every failed part and likely failure point on an older Johnson 25. So far I’ve done the water pump and impeller, carburetor rebuild, spark plugs, fuel lines, coils, fuel pump, thermostat, cylinder head gasket, and propeller. All of the parts I’ve ordered from Crowley Marine have arrived on time, and been exactly the parts needed for the job.

Problem fixed: 300 hour service

I use my engine in saltwater so I did the entire recommended service list, not just the 300 hour. It runs like a top. I will be needing a new lower unit in the next year or two due to saltwater corrosion. I've looked them up and they're readily available brand new. Pretty good for a 14 year old engine!

Ok. End result for parts was great. End result for costs was not ideal. I was sent the wrong part, that was ordered and invoiced correctly.....paid the shipping and duties to get it here(Canada)......then was shipped the right part and had to pay duties a second time and am left with a spare part that I don’t need or want. Paid too many fees to get the orders that I placed. Thanks for sending the right part right away though - that was great. Don’t make me pay again for it though.

Problem fixed: overheating and leaking lower unit seals

By using Youtube, I was able to accomplish the repair with medium effort. The thermostats were a little challenging to replace but got it done in 1 to 2 hours. The most difficult part of replacing the lower unit seals was getting the old seals out of the unit. Once done, the new ones went in easily.

Problem fixed: see repair story

I had to remove the water jacket housing at the rear of the motor as gasket was leaking a bit. It has the spring and thermostat in the lower cylinder port. The engine cover latch prevents easy or any removal. (later engines moved this up to top cylinder). I got it our with difficulty and of course Crowley have the replacement parts. Getting smarter now so taking it to my mechanic for replacement. In the end I don't think the leak warranted going to this extent to repair. Some gasket cement would have done the job. But live and learn!

Problem fixed: No water telltale, over heat alarm

This engine had been sitting since 1998, started right up but little water pumping thru, and overheat alarm went off. Pulled lower unit checked pump, it was ok. Figured it may be the thermostat, pulled outer head and found loads of sand, and the thermo itself looked like stone. BTW only broke one bolt but not down so far so I could drill and remove it. Blew it out, then ran water thru it. Replaced thermo, spring, gaskets, pump impeller, also plugs, fuel pump and replaced a cracked starting gas lever. Runs great!

Used the tech tips and exploded views to figure out what parts I needed to service the Evinrude E-tec 90 hp. The phone support was excellent to make sure we I got the right parts. Changed water pump, thermostat fuel filter and fluids. All the parts and advice came from Crowley’s.

Problem fixed: No cooling water circulation, gear case oil leaks and rough running.

Unit had age related corrosion in the cooling system water pump housing which also requiring helicoil repair of corroded bolt/screw holes. Thermostat and housing gaskets replaced as preventative maintenance. Seal degredation in the gear case required a strip and rebuild of the gear case with new seals. Now while I am at it, the old girl from the class of 75 will have a carby strip, ultrasonic clean and rebuild to eliminate some age and 'old fuel' related contamination of the carby. Sweet. Never overlook preventative maintenance and servicing. Crowley Marines web site IPL and customer service got the ball rolling. Easy as. No rush, take your time and do a good job. Safe boating all.

Problem fixed: Poor water pickup. Not much water coming from the tell tail.

Removed gearbox lower leg to replace water pump. Replaced pump and gaskets. Although the gear was left in neutral, I found it difficult re-locating the drive shaft and gear selector into the power head. Found it slipped in easlily when the engine was turned upside down and shafts lowered verticall downward. Also removed the exhaust cover outlet assembly and de-clogged the water valley area. NOTE: This motor is susceptable to salt clogging because it is difficult to properly flush the motor with fresh water. "Ear muffs" can't be fitted due to the location of the water pickup. Circulating the water in a bucket or tank/drum can be limiting to correct flushing. Also replace the clogged thermostat which had also suffered from salt corrosion.

Problem fixed: poor water flow through motor after water pump replacement

when you remove the water pump impeller if the vanes are disintegrated to any large degree. (ie) pieces missing. The fragments are most likely up inside the motor. These fragments cannot pass through the water restrictors in the bottom of the block. The blocked restrictors limit or totally block the water flow through the motor. The only way to remove the fragments is to back flush them out of the motor. I did this by removing the water cover and the thermostat. Then I ran high pressure water from a hose into the block at the thermostat opening. I put a 5 gallon bucket under the motor before I applied the water pressure to be able to see if anything came out. Sure enough everything missing from the impeller blew out into the bucket. I reassembled the motor and it had good water flow and cooled perfect.

Problem fixed: Thermostat failed...overheated engine

Removed the head, shaved it (I took it to a machine shop where they have a large belt sander table with diamond sandpaper. Paid them $20 to clean it up. It was not warped or anything. Just did it because), removed the water plate and cleaned up contact areas and replaced gasket and thermostat. Replace some worn parts in the water pump area and installed new impeller.

GREAT! I placed a small order and the prices were good and shipping was great. I like the fact these are factory parts and not after market which I have had some bad experiences with in the past. I just placed another order two days ago!

Problem fixed: Motor was running too hot

Very east job. Just be sure to get the thermostat, seal, & gasket as I did. After I removed the old one I flushed all the passages with my water hose and then compressed air. Probably could have been done in 20 minutes or less but I don't have to hurry anymore!
