Well engineered rig that is timeless classic Formula...good job...enjoy the fruits of your labor.

So I thought it would be good to update the thread after 3 months. The boat is still running very well. I had some ignition issues to work through, turns out both original coils were getting tired and after extended WOT runs it would start crapping out. A pair of new coils have cured those issues. I have put about 40 hours on it so far this year, so it hasn't spent much time on the dock. I ran a poker run with it and it ran flawlessly. I did break a trim tab indicator cable, but that is going to have to wait until the boat comes out of the water to fix that. I am also purchasing a trailer for it so I can start doing a couple of poker runs next year.

The one change I have made is in the silent thunder platform. When I had it off last fall I cut the dams down inside of it, but it really didn't change the sound. One of the things that did bother me was the sound of the rubber flappers well, flapping. It sounded like this:

Kind of like two big blocks farting at an idle.

So this weekend I pulled the flappers off and I was shocked at the difference. It really improved the sound at an idle, it has a great rumble to it. Even my 12 year old daughter picked up on it right away and said the boat sounded better. I am sure it is louder on plane, but I can't tell from the drivers seat. It is still muffled and shouldn't get me in any trouble with the local po-po. This is how it sounds now:

Kind of hard to tell but it is way a way better sound without the annoying flapper noise.

After this season I am going to yank both motors one more time. I overlooked upgrading the coolers and lines, and I won't be happy until I do that. I will also check the bearings while it is out to make sure nothing is hurt and install the hardin cooler kits with -10 lines and larger coolers. As much as a PITA as it is to winterize these motors actually yanking them isn't that much harder. Other than that I am thrilled with how the boat came out.

Sounds great!

Sounds good to me nice job.

I thought that was the way you winterized them? I have never left my motors in the boat over winter before. Actually have become pretty quick at pulling them. LOL

We have it down to a science , almost like drag racers[ATTACH=CONFIG]528358[/ATTACH]

Good job with all that work and it is stable now. Many happy days boating.

Last time my engines were out, I made pig tails for all the drains (oil, 2 block drains, each cooler drain) for each engine. Used brass hardware, and 4'-6' hoses. Put a threaded cap on the end of each hose, and route them carefully up along the engines with zip ties when not draining them for winterization. (Careful to only open one at a time to ensure good flow of water out the hose. If the flow is interrupted by clog in the block, hit the hose with a blast of air compressor air to help clear the blockage.)

Anyway, winterizing is very easy now compared to how it was. Think all engines should come this way.

That sounds like a brilliant idea. Fortunately my coolers are up top, but the block drains are a giant PITA to get to on this boat. That is part of the incentive of pulling the motors, they suck that bad. I could see rigging some hoses up for the block drains and a hose out of the oil drain plug to a gate valve with a fitting for oil changes. I

may end up getting more aggressive with the cams in pursuit of more top end. The midrange is almost too strong right now and I always baby it out of the hole just to be gentle on the drives and transmissions. I am also hoping to convert the motors to Holley EFI if finances permit.

As much as I enjoy the boat, I really have my heart set on a Cigarette. I decided to throw my boat up for sale, if it is meant to be it will sell, if not I will keep using it and improving it.
