    Well I wonder if there is such a thing as to much power? I guess we will find out....

    This is the third repower since its restoration. The first was a 160hp Cummins diesel that was just a slug then the 260hp 5.0 MPI and now the 415hp 383 small block.

    Very cool (and super clean) boat. Hey if something's worth doing, it's worth over-doing.

    Since the boat had a diesel and sat with fuel in it for a few years I have a very bad algae problem. I added an extra racor fuel filter but I have to change filters every few hrs and because the 5.0 was fuel injected I always had problems keeping the correct fuel pressure!

    I decided to build this auxiliary fuel tank that will continuously polish fuel all the time with a separate high pressure pump circulating into the racor and water separator, then back into the main tank..... Hoping this cures the issue and keeps clean fuel entering the carb??

    Well there went a couple hours! Reading and looking up the B20

    Great platform. I'd love to hang an outboard on a bracket on one. Wonder how that would be?

    It's looks like a carbed motor.....I'm completely unfamiliar with inboard motors, but is there a reason you did not go EFI. Beautiful setup you have there....about the sweetest 20 feet I've seen.

    Thank you, a lot of work has gone into this thing. I hope to get it worked out soon.

    I decided to go with the carburetor since I am having fuel delivery issues. I had to replace two high pressure pumps due to overheating when the fuel line would clog from Algae. I had fuel issues almost every time I would take the boat out and I really don't feel comfortable going any distance from the marina. I want simple and reliable! I bought the carb and manifold with the intent to take the EFI off the 5.0 and run a carb then decided why not just get the power I want and put the big motor in.

    The boat will be used as a tender on a large yacht and spends a lot of time in the sea of cortez and pacific Northwest where for the most part ocean condition are very calm. I am hoping the extra power is reliable and gets the boat close to a 40 knot cruising speed?

    fuel sump / polish tank is done and ready to mount. My guess is around 10 gallons and maybe 8 usable. With this and the 75 gal main tank I will hopefully get at worst 150 mile range if I can burn 2 gal a mile @ 40 knots and possibly further running 25 to 30 knots.

    I agree and love my center console with outboards but this particular boat is a classic and would be a sin no matter how much sense it makes running a outboard.

    Looks good. If it was still diesel I would have said add Biobor jf to the fuel.

    Got the fuel circulation pump mounted and all the new fuel lines plumbed. The motor is all together and ran it Tuesday only realize we had the wrong harmonic balancer. I got the correct balancer overnighted and she runs pretty good on the stand. (glad because the motor was jumping all over) It is amazing how bad a engine will shake when a few ounces are missing from the crankshaft!!

    Planning on getting the motor in the boat in a few days. I still need to wire the fuel circulation pump and fix the steering ram ratio. The hydraulic steering ram does not have any adjustment to center left or right creating the drive to only turn about 15 degrees to starboard and full lock to Port. I have been dealing with this for quite some time and I am pretty used to running the boat this way. As much as want to get the new motor in, this is a perfect time to address the issue. I will get some pictures of the solution as soon as I figure out the solution....

    Motor is in the boat but after running on the stand they took off the risers to find water sitting in manifold. I guess because there is a lot of cam shaft overlap and the stock risers mix only a few inches past the turn, it is creating water reversion back into the manifold.

    I will have to build my own stainless risers now

    I was able to come up with a fix to get the steering ram equal stroke on both sides. I am looking forward to turning right now!! image.jpeg

    Here are a few more pictures of the fuel catch tank and pump all done and plumbed. This is run off of the ingnition switch with a override kill switch.
