Willard 7m seaforse repower.

This is an un original post other than the fact it does not seem to have been done with a Volvo D6. I hope you find this amusing. Chris Loyd was my inspiration. I was heart broken when I heard his very cool Willard was lost in a marina fire. Damm.

My cummins 5.9 was in fact great. Enough power (just) at 220 hp on cummins reman. 300 hours on the cummins panel. Ran great but you had to wear hearing protection after 10 minutes. Loud !
Had an oil leak. Not much, just enough to cause this environmentaly conscious guy a problem. It drove me nuts actually. My stuff does not leak! It was a plug on the oil pan that was only finger tight. ARGH ! Did not know it was there.

Cummins is now out. Now the complex part of putting in an all electric , computer controlled , used Volvo begins
.This is where the the amature mechanic is excluded. I will expand later. Computers and proprietary harness abound. Be ready if you are a Volvo penta customer. It is very, very expensive.

The D6. It fits :)

It fits.no clearance issues other than the junction box for the trim motor. Just needs to be located back about 1 inch. Dry Exhaust will now have to be modified in a similar way to chris's QSB.

now the exhaust.

where to begin... Engine is in now what....

I have now learned from those who really know.....it is not a good idea to put anything fiberglass within 30 inches of your mixer. If inside this distance ,It may last or may not. use 30 inches....ok. So my fiberglass 90 is now useless. I have about an 8 inch gap. I was uneducated when i bought it...

Tasks to make this part of the project work:

I need to reposition (cut/weld/brace) the stock Volvo 4 inch exhaust riser so the mixer is farther aft and centered. This is not new. This is what seaboard marine did so excellently for Chris, clloyd years ago as per his great posts ..... I need 316l stainless tube for fabricating....nope not around here by the foot. 20 ft lengths minimum. argh. I need 3 ft max and that is allowing for errors. $30.00 a foot...you take 20ft. FaK !

It also seems 5 inch od 316L stainless steel is like unicorns farts, rare in these parts too. At least in any practical length. I can buy a 20 ft section for $180 a foot ! Obviously the local suppliers are trying to tell me something. Plan "B".

I have spent some time kicking tires in the Florida boat scene. So.

De Angelos exhaust specialists in Ft Lauderdale. Florida, the land of plenty when it comes to boats of all shapes and sizes, but often big. 5 inch is big on the great lakes, average in Florida, hence lots of 316l tubing stock.

My 4 and 5 inch tube is on the way to me. Thank you FEDEX air. thank you De Angelos.

Pics are of the 5 in. hole I had to cut. measured about 20 times before I picked up the hole saw.

The fiberglass 90 exhaust I had planned. nope. Anybody need one ?

The 90 will now be 5 inch welded stainless. (solar flux to weld with, instead of purging with argon...) second best i know.

Last pic is a very strange pic threw the exhaust cut out. Not a common viewing angle. I like it. I see a spot I missed scrubbing.

More fun to come. D.

exhaust now fabed up

Exhaust is now fabricated and finished (not like in the pic) and has been in and out now for fitting and all the other details that need looking after. The black plug will be used to plug the old exhaust outlet. Turned down to just the right size. It will be put in with 5200 sealer and bolted into place. I have a nice down slope from the elbow all the way to the back of the boat. From the elbow it goes into 5 inch tube, then into the rubber muffler, a short section of silicone hose then out. I will post pic of the complete system soon. The next challenge is to route cooling water for the gear cooler then water into the mixer. There is no room for the cooler behind the engine.

There is always a challenge.

Looks great. The newer cummins are also quieter and it would have been less fab work probably. Why did you choose penta?

Why Volvo ?

I chose Volvo because it revs to 3500 rpm. Typical Cummins is 3000. Yes it would have been easier to drop in a Cummins right onto the old mounts.

A wider operating range allows for less prop and less stress overall on the drive train. The downside as i am finding out is the cost of Volvo rigging parts. yikes

Exhaust riser now all wrapped up. Exhaust is now in. Gear cooler now fabed up. Cooling water from the engine is 2 inch diameter and the cooler is 1 1/4. had to make up a splitter to not restrict the flow. Just have to mount it now.

The Cummins 440/480 QSB 5.9 get 3400 rpms. Or, if you wanted to maximize rpm, you can get a ZF280-1 with a 0.814:1 (instead of a reduction gear, it increases the revs). clloyd looked into one of these transmissions but there was an 18 mo lead time.

But that Volvo is going to work just fine!!!!!

3400 rpm for cummins, true

Hi NCP.

you are correct. I guess I was referring to the older Cummings stuff that I could actually afford and more importantly find. New was not a practical option and used also was a bit pricy. This Volvo fell into my lap for a song. I could not say no. The used marine engine market is thin in Canada and the Canadian dollar is weak compared to the USD. Buying local made sense.

Nice work, it's good to see some serious boaty stuff happening.

Are you familiar with heat resistant silicon self amalgamating tape? It works nicely over the exhaust wrap to prevent it becoming soiled and generally grubby and frayed over time. I think I've a pic somewhere, I'll have a look-see and post a pic if I find it.

There ya go, easier to find than I expected. It's black and in shadow so you'll need to zoom in to see it. It's been in place for 4 years and looks just as tidy now as it originally looked.

Keep your story coming!
