Nice! That's the way to do it.

Snipe, where did you get your engines?

I'm very jealous. Did you get your motors from Seaboard Marine as well? Those controls look top-notch.

Sorry if I missed it. Are you using gelcoat or paint, you said you were buffing?

Where does the rear bilge pump discharge? Also I love that deck. I think that how I'm going to do mine. The removal deck is nice, but that it very clean looking.

I think the fuel burn numbers from JimmyG's boat may be for only one engine. The fuel burn curve is at the link below.

For those with their batteries in the bilge between the engines, do you have any concern about the batteries being submerged/shorted in the event of bilge flooding?

Anybody have any other ideas for getting heat to the flybridge? I was thinking something along the lines of what Mike said with the 4" PVC going up to the bridge.

I did this years ago. I put the heat exchanger / fan unit in the head, under the sink. I ran flexible duct behind the fridge. One vent goes to the V-berth. One opens in the cabin, just forward of the head. The third connects to 4" pvc pipe that runs up to the bridge and then out just below the helm...

All, I am working on rewiring the boat now, and have also decided to add a hydronic bus heater to the boat. My boat is simple with minimal electronics, no gen, gas 454s, and no AC. I would like to add heat to make fall and spring trips a little more comfortable. I selected a 40,000 btu hydronic unit...

I think Jim Swagler, (not sure if he's on here), just did a faux teak toe rail on his 31 that looks great.

So if the frames are too difficult to entirely remove, how would you go about removing the existing glass and replacing it? I guess you could reseal and paint the frames in place...

All, Following up on the other windshield frame thread, I wanted to ask for some guidance on removing the aluminum window frames from the boat in order to replace the glass and paint them. All of the windows appear to have been replaced over the years with plexiglass that has since crazed and cracke...

Stephan,

I agree about keeping the boat light, but my boat already has a custom top with an enclosure that undoubtedly hurts speed but makes the fall and spring season much better.

While I agree the big block torque is unquestionable, look at the power curve for the DI 6.2. This motor is not the 6.0 LS of old, this is a new technology, LS block. The power curve shows it at 450 lb-ft of torque at 3000 RPM. I don't think the old 454s made any more than that. Crusader 454 = 350 H...

Chuck,

Do you have more information on your setup? trans ratio, prop pitch x diameter, measured fuel burn?

My goal is a reliable, 24-knot cruise, at 1mpg.

My goal this winter is to get the old 454s back into shape with fuel monitors, and see how attainable that may be.

I have heard references to Pete Fallon's boat, but can't find any information anywhere. Can someone point me towards a link or describe Pete's setup?

Hey everybody, I started a thread a little while back discussing 454s in these boats. Let me preface this by saying I would love to put diesels in the boat one day, this discussion should be about gas motors for now. This discussion isn't about saving money by repowering because in reality very few ...

I am going to run the boat again this afternoon and check again. Maybe there is an inaccuracy in the photo tach, or the boat is steeply overpropped, it’s hard to nail down one variable sometimes. Thanks for all the input.

So I think the one working tachometer I have been using to gauge my RPMS is reading approximately 500 RPMS high. Using a phototachometer, I am getting 20 knots t 2600 RPM.

I ran the boat again all weekend and she ran great. The tachs are a little wonky and will need to be replaced before I can get accurate speed numbers. At what I approximate to be 3000 rpm I am getting 18 knots and at 3200 I am getting 20 knots. I have no idea if this is accurate or not. I will repla...

She arrived yesterday. I am going to do some maintenance to the engines and will get some updates on performance numbers. I need to figure out how to network fuel flow senders, I am not sure if the current gps is modern enough to connect to nmea 2000 senders.

Carl, Yes, agree on the smell. In my experience the smell of diesel exhaust I am more sensitive to, however, that would never stop me from buying a diesel boat. In this case, it’s simply the cost delta. The gas motors will be more than sufficient for the boating I do. You’re right, I can’t justify t...

Bob, I’m not sure what you mean with your comment about diesel smell. The only diesel smell I know is the smell of diesel exhaust and most of the diesel boats I’ve been on had some diesel exhaust smell to them. (I worked at Viking for a couple years and even those had a diesel smell sometimes.) That...

Some of you guys reporting 24 knots is great. I would be happy at 20 knots but it's nice to have the extra if you want it. What is everyone's specs? Motor year Rated power trans ratio propeller type, no. of blades, pitch, diameter? Anything else of note? Has anyone tried acme props or 4 blades? I sp...

Thanks, guys. Sounds like 1mpg might even be realistic, but in the ballpark.

Boat has the tank replaced, bu t the deck was replaced with starboard, which I would like to redo.

All, Have the opportunity to purchase a 31 FBC with twin gas 454s. Motors are 1996 crusaders. First, what are realistic performance expectations of a 31 with 454s in terms of speed and mileage? Does anyone have any speed, rpm, mpg info they would be willing to share? I have heard 1mpg thrown around ...

The inboard Moppie 26 is definitely an option. I much prefer the looks of the 25 flybridge though. Both boats are hard to come by in inboard configuration. The search continues.

Has anybody seen this boat before or does anybody know any details? I have been looking for a 25 inboard SF for a while and stumbled upon this today on Instagram. I have even considered converting a boat to twin straight shaft inboard with the engines spaced like a 31 to free up room in the cockpit....

I am in New Jersey. I am willing to travel to find one.

Hey everybody, I just finished restoring an older mako inboard and would like to make a 25 inboard in some variant my next project. Does anybody know the whereabouts of any 25 inboards? Most of the boats have original 318s and are due for repowers. I imagine a pair of Mercruiser 350s or 383s @350 HP...

I was wondering the same thing.
