Not happy with the deck condition, it's flat i checked that but there is some pitting. I have a set of cometic gaskets l always use copper coat but I'm concerned about leaking with these pits, I've assembled plenty of car engines that looked like this with no issues but this is alot of work to take back out if I have problems. If I had more time I'd deck it. Reason for post is I'm considering just using a felpro marine gasket, 17048. I've never had any problems with those gaskets. Engine is getting afr heads with head studs.

Option 1 cometic with copper coat and a skim coat of rtv around water ports, very thin skim.
Option 2 just use a felpro marine 17048 gasket.
engine will be around 750 hp 5-6 lbs boost with the tbs 250 blower.

it looks worse in pic, you car barely feel them and the block is flat. I also have a merlin block 555 short block ready to assemble i was going to put in boat in couple years but this engine only has 112 hrs on it and has a bunch of life life
compression was 140 accross board with very low leak on leak test.

"Miami Vice 85" has been announced featuring some young actors and supposed to be set in mid 1980's Miami with a storyline set on the "Brothers Keeper" episodes. Would be cool if it turned out to be a decent movie. They're saying it will be shot in IMAX. Supposed to be directed by the same guy who did "Top Gun Maverick" a few years ago which I kinda liked. He also directed "F1", I haven't seen it yet. What's your thoughts? I want to be optimistic but I'm old now and hate just about every movie I see :)

Just some info on an increase to my fuel capacity with the addition of three vinyl ester tanks I’m
constructing. I picked up a CoPart special awhile back and have been going through it. It had twin 275 Verados and now has trip 350 Verados L6’s, 0 hours on rebuilds. I plan on taking the boat offshore and wanted the third motor mostly for redundancy, this boat won’t plane with a single motor and a load. Standard fuel capacity was 261 gallons, 186 main and 75 auxiliary transfer. Not enough even running on 2 for the range I’d like.

So I located 3 areas where I could fit custom sized tanks.
Starboard side seat

Cooler area under seat front of console

Port 2 step to fwd deck

The step and seat areas were hollow and accessible by removing interior cuddy trim panels.

I foolishly thought initially I would be able to lay up in these areas, impossible for me. So then I figured out that I needed to make plugs. I used 3/8 Nidacore to make the plugs. The 3/8 was flexible enough to conform to the curvature and angles. It was also the maximum thickness the tank walls would be. I expect less than 3/8. The areas were then furred out with 3/8 Nidacore strips and hot glued in. The 3/8 strips would approximate the tank thickness after laying up on the plug. I used some 1” Nidacore on the hull side for a little wiggle room. A temporary floor and bulkhead were added.

The plug was formed using pieces of Nidacore hot glued to themselves with wood blocks, obviously, and not the furred out pieces. It was cross braced for stability.

All of the plug cornea were cut back 3/4” to allow for fiber strand bondo squared off


I was now able to radius those corners 3/4”

The Nidacore plugs were skim coated with bondo and primed.

By now I was sick of Nidacore and bondo so I used some 3/4” plywood for the cooler plug. I had some angle brackets kicking around so I used them so I could knock down the plug from the inside if needed.






some additional photos of the air lines I installed to aid in part removal. The attached fitting is only used to assist with the plug covers when removing if required. The holes will be taped over when laying up the tank, not the covers which will be a separate layup. Since this is my first endeavor of this scope I wanted to give myself the best chance of having minimal problems. I don’t know what the cost would be if I had someone make them for me.
Fuel manifold
Fuel manifold

I elected to make a fuel manifold using motorized ball valves to control distribution. These are equipped with manual bypass, easily accessible, in the event of failure. I am installing a second fuel pump for these tanks with crossfeed capabilities between all tanks and both fuel pumps. Since I’ve gone this far I am adding fuel sending units. The geometry of the seat and 2 step tanks do not lend themselves to standard resistance sending units. So I am going to use the Holley lidar easy level.




I calculate an additional 125-120 gallons giving me between 386 and 391 gallons total. The tanks are being constructed to Coast Guard regs relating to fitting placement, baffles, etc.
Hopefully making the tanks in a week or two. Need to make a material list. Anyone need plugs or tanks?

Thanks
