LOVE IT!

I also love that you have a spare b-series block laying around to use for "mock-ups"...


...PS...(so do I....LMAO...in the loft in my garage....HAHA)

Nice work.

Having an extra block laying around is always helpful.

Looking good...I certainly don't miss that part of the build, then again I don't miss much of any part of it.

Really nice. I was hoping you'd put motors with pistons in the boat, glad to see the complete engines in the latter pics, lol. Really nice work, a very lucky Bertram.

I bought the boat five years ago in Margate N.J. From a guy named Frank Gallagher. This was a picture when I bought it. The name was Vixen. Image

I like the battery box. Did you build it or buy it?

Re: Cummins repower

I built the battery box out of coosa and glassed structural fiberglass angle to the hull and bolted the box in so it is removable. Image

Looking great! Super clean install! When do you think you will be ready To launch?

Thanks Mark I am going to try for late summer for a sea trial but I guess it depends what I want to get finished 100% I am thinking just get it in the water then finish up other projects as I go. But the other half of me wants to finish everything first which means next year some time. I guess I will keep plugging along and see.

How about some updates... you are living my dream build! LOL When I move out of the Socialist republiK of NY I am gonna do a similar build...Your pics look similar to my repower on my B28. In my yard behind my house...Love it! No better place IMHO, I got all my tools, air, electric....everything!

Anyway, I know your busy but many are salivating for "snipe" to get wet and post some numbers

I agree, great looking work!!!

Do you have a couple of extra hours to come by and finish my boat? :)

Thanks guys!! It definitely is a lot of work I wish I had spare time it all goes into the boat. I can’t wait to be done so I can just enjoy it.

Pretty Work Jason, happy to see another 31 getting the attention and dedication on a re-build they truly deserve. Looking forward to seeing and hearing about all the hard work your doing! Keep the pics going. EarleyBird 🤪

That is really nice work. It looks like you are not a novice at using fiberglass.

Thanks Tony hope your on the mend now. When I finish up I hope we have a rendezvous and I can meet some more of the guys!! In the meantime I will keep pushing ahead. I wired up some sensors on the engines I am adding boost pressure,gear oil pressure,gear oil temp and exhaust temp. I also started prepping the bilge for some awlgrip. Just waiting on a good day to paint. I got the backer pads installed for the sea cocks and made a few little pads with recessed studs for the bilge pumps. Image Image Image Image

I love those backer pads.

Re: Cummins repower

Nice work on the pads. Looks similar to the ones we made using the fiberglass plate McMaster sells. Except I did not add the studs before they were glassed to the hull. I drilled and tapped them and screwed the bolt into them.

Thanks Cam. Tony I used Garolite G10 from McMasterCarr and I drilled and tapped them as well I think they will work out nicely I bonded them in with west system Six ten. I plan to do them all the same way.

Shot the cockpit with 545 over the high build and did a final sand. Also primed the gears with 545 and sprayed awlgrip on the gears. Nice weather up here in the northeast this weekend. Hopefully this week I can spray the bilge and next weekend put the engines in for the last time. Image Image Image Image Image Image

Nice work on those engines. I regret not repainting mine when I repowered. They looked pretty good, but that Cummins paint just does not hold up.

Re: Cummins repower

Tony I wish I painted the engines with awlgrip as well but I only did the gears. The engines are rust-oleum if they don’t hold up well I will just pull them and repaint with awlgrip next time.

That Americoat 450H I think would have been a great choice to paint the engines. If I ever paint engines again I will only use 2-part paint.

What do you have lurking under the car cover in the garage? Old Bronco or something?

Jason,

There are still hundreds of these little devils running up and down on the gravel roads and the rocky slopes of every Greek island...mostly rented by youth who can withstand the kidney toll.

My ex wife had a two stroke one in her youth too, a buddy just bought the newest version last year, which if you ask me, is 95% the same as the older model.
I took it for a ride and re-confirmed that with my back situation I’d rather abstain from such “devices”, there are people however who swear by it. My ex included.
I’d rather stick to my forester...

Yannis it was a fun project it does ride slightly like a cement truck but fun!!
I painted the bilge with the awlgrip this week and put the engines in the boat today even got the wife to help out.Tomorrow I will put the shafts in and start the rough alignment. Then I need to start building out the helm!! Image Image Image Image

Looking at your wife's expression she is really into turning wrench's or she is cursing you under her breath.

What are you doing for gauges? Twinscans are nice to save space. Unless you are doing all digital...
Single arm controls?

My wife pitches in every fall when we pull the boat and in the spring to get her ready to launch. In fact in her younger days, she used to help paint the bottom. Now it is waxing and helping with odds and ends when I need an extra set of hands.

Tony i am glad my wife loves it or i could never pull this off i spend a lot of my free time on working on the boat! Frank I went with the SMX digital gauges from Sea Board Marine. The controls Are Rollins super nice. I will be building a helm pod in the next few weeks. Image Image Image Image Image Image

Got the alignment right on today. I will check it when I splash and make adjustments. I also installed the dripless today. Baby steps but I am at least moving in the right direction! Image Image

Jason,

I am VERY impressed with your "get it done" attitude. Your work is exceptional on both your marine and terrain projects; and a very impressive shop helper as well. Can't wait to see the performance #s when you splash your 31.

Thanks! Tommy I keep pushing ahead trying to get her floating again! Today I bed the rudder ports and dry run the props. After family time at the beach of coarse. Image Image Image
