Default Wellcraft V20 rebuild

Hey guys,
I have a thread over on Wellcraftv20.com but I thought I would share this rebuild over here as well. I'm only at 8 posts so I'm going to spam a little to get to 10 for the pics.

The boat was given to me three years ago.
My family is has been extremely lucky to get the last two seasons out of the boat with out much needing to be done. This season ended a few weeks ago when I F^#@ed up. The 86 seadrive was overheating, and I couldn't find the problem. After doing everything I could think of, I pulled the head covers to look at the cooling channels. Well two of the piston sleeves had small cracks at the very ends. Ok well I knew the engine was on its last life, but I killed it when I broke a bolt off in the cooling head cover. I tried to drill it out and some how punched a hold though the the head cover. Yeah I messed up hard. So I'm going to start the rebuild next week. I have a flotation stainless steel marine 30 in setback bracket I'll pick up in Dec. The transom is mush so I will start with that. Putting in an order at US composites for 5 gallons Vinyl ester, 25 yards of 1708, 1708 tape, and micro balloons.The engine is where I still have a lot to decide. There are three main options I'm looking at. a newer used optixmax, a new mercury 4 stroke, or a new Suzuki df175. All are 500-550 dry weight so it really just depends on what i can get.

you guys have any thoughts before!


My work computer is not loading the pics so ill get them tonight.

Any current issues with water coming in the corner scuppers when standing there? A 30" setback bracket with 500+ pounds may increase that problem.

maxie,

The deck drains into the bilge. The great thing about this conversion is because of the seadrive I will only be adding about 150 lbs of weight. The seadrive weights about 495. the weight of the bracket is close to 100-150 ish lbs. It is a flotation bracket so they should be very close to canceling out the added weight.

Deck drains into the bilge? That sucks...I had an outboard version directly on the transom which drained overboard......but feet did get wet when standing in the corner...thats why I asked ......your seadrive is close to the transom...your bracket will put 500lbs sticking more than 2 feet past the transom...that will cause the ass end to sit lower in the water...its a comparatively light boat at around 2000 lbs and only 8 feet wide/20 degree transom.....If possible, I would go for a 24 inch setback and full width maximum floatation bracket...not one of those skinny single engine brackets...I believe 24 inch should be OK with getting full tilt up without interference.

Will the bracket provide extra floatation ?

Hum.... you could put the boat in the water, and add that amount of weight by sitting people on the transom to roughly equal that weight.
See where your scuppers sit with the approx. 600lbs sitting on the transom ( 3 guys should do it )

Then, have 2-4 additional people get on board, which will represent motor plus people.
Do this with a full tank of fuel so you're working with " worst case scenario"

I have a V21 ( same boat, different transom config ) Had a 150 on it, now a 200. Trim tabs took the boat from a very average ride, to a very good riding rig.
Best of luck to you.

Got the cap cut off the stern. Was not as hard at I would have thought.

I cut forward a little to get access to the last bulk head and transom knees.
I cut where the rod box was so hopefully it will reduce the fairing when it goes back together.

Going to start cutting the knees and last bulkhead out tomorrow if I have time.

This is the second V I have worked on like this, and I canít believe what passed As quality. The stringers where open in 4 or 5 places, the bulkhead tops where just cut off & left exposed, and all the drain holes drilled where unsealed. I canít believe the boat is as good a shape as it is!!
Iím really HOPEFUL about the fuel tank. The foam is dry and the top looks in great shape. Iíll pull it and really inspect it since Iíve come this far. What are poeples options on the coal tar epoxy?

Why did you cut it the cap and flooring out. When I had to replace the transom on my V20 we just hoisted the entire cap out with no cutting needed.

when I started, I knew I had to redo the transom. One to beef it up for a bracket, and two is was soaked. But when I was drilling test holes in the stringers I only got wet wood back near the transom. I was hoping I would just have to do half a stringer rebuild, but I should have known better. Once I started cutting everything out I realize I would have to redo everything. In hind sight I really should have just pulled the whole cap from the start.

Very nice! I like what your doing with it. The bracket looks good on that hull, I think it will work well.

Whats the white and gray on the bottom?
