The challenge as I see it is to figure out what you need to support that front motor mount and how high off the bottom of the hull it needs to be. One way I've seen this done is to have the 2 bolts in the back engine mounts loosely and put the front of the engine on a hoist with the front motor moun...

ahh..... the pain. I finally had enough of my IOs and went down the outboard path after having a coupler go bad for the second time. This is the area if you mess it up, you will revisit it. so build it and build it well. What does the engine bay of the 20' look like? can you share a pic? I have the ...

I recently took out the core of my transom and put a new core in, cold weather has put my project at a standstill so it is not quite finished. I've done quite a bit of glassing and working with epoxy so I didn't think much about doing this project, but if I were not experienced I would not have take...

sorry for the slight derail - I am thinking about the possibility of a similar jackplate and not doing a motor well on my project. in looking at the pics from the profile perspective, it seems that the combination of the 10" of setback + the lift, they both might be enough to allow tilting the motor...

ktm_2000

Between what I've read and what Bruce has posted, It seems there is a lot of flexibility in how high to mount. You've put yourself in a great position with the jackplate and its 7" of travel. I'm guessing with the jackplate you could adjust the height fairly easily with some wrenches. I would start ...

ktm_2000

I just re-read your post, you have a bob's jackplate. how much travel does that have? can it go both up and down?

If it will only go up, I'd mount the engine as low as it could go and then fine tune to the correct height via the jackplate.

ktm_2000

Cam, based upon my research you are pretty close, maybe 1/4-1/2" too high. I'd roll with it and see how it does, the best part is that you have another hole on the outboard so no matter what it will work. Standard install without a bracket the anti-ventilation plate should be 1/4" below the bottom o...

must be, mine is considered to be a 64, hull number 25-455 and was built in late 63. I have a tag that is very similar to Cam's on the center stringer under the cabin hatch.

I originally had 2 of the tanks that Hotspot has shown, on my boat they were labeled 46 gallons each so boats with that config should have had 92 gallons originally. I saved the bronze fill and pickup plates as well as the bottom ring that they bolt to if anyone wants them. Bertram bedded the tanks ...

ktm_2000

When ethanol came through I removed the original tanks, chopped out the center stringer and made a flat base for a larger tank. There is another smaller stringer inside the main hollow fiberglass one (tough to describe -see pic), during that time I left the fiberglass one level with the top of the i...

Cam, I'd appreciate the diagram for your bilge pump, my approach has worked as a high water alarm as well, I do a lot of live bait fishing and regularly ran with the scuppers plugged and had occasions where the portable livewell shifted and the output hose was sending water inside the boat instead o...

with this discussion, before I owned my boat one of the caps went missing, anyone know of a replacement option?

ktm_2000

goals: Save @$200 in wire, neat and clean, get the ease of maintenance of being able to test connections at the connector blocks in bilge. The savings isn't as important as the other 2 and it seems that if I just put the connector blocks in the traditional setup I would get that anyway. as for your ...

gotta love required 2+ hr project meetings where my input is sub 5 min because of this extra time, I made a more pretty diagram to describe what I am proposing, I thought a bit more about it and have even more components to cover.

I've got a B25 where my house batteries / switches and panel will be forward in the boat, some of my main loads will be aft in the motor well, like main bilge pump, crash bilge pump, washdown pump, livewell pump. My thought is that I could run 2 higher gauge 2 wire sets back to a connector bar which...

I knew my memory was correct

Coolair, how much did Cap't Pat charge for it?

I'd have no problem donating to the site for a copy of the materials.

Bruce, what would we need to do to make this work out?

ktm_2000

Pete, While I don't like your answer because it will stretch out the timeline of my project, I agree with you that it is the right answer and need to wait. The links that Tony Meola put up from west system cautions states that I probably could do the work in the temps that are around right now but i...

several of you have expressed concerns with electric heaters, what is the concern? is it the extension cord? and getting power out there cleanly and not tripping breakers. Or is it the heater?

no pics but I got the 2nd 3/4" plywood panel glued in last night hubris definitely got me, I didn't treat the bolts with any non-stick so they were stuck into the first panel.

I've looked at the porta-bracket and am concerned with too many moving parts / failure points. Isn't Soren from an area that even though he is in ocean, the water doesn't have a high salinity and the corresponding corrosion problems?

Cam, It would be interesting to see how it all goes together with the engine on a short setback bracket. I'd like then engine on the transom for fishability and if I needed to do any repairs but I would also love to have a large un-interrupted cockpit. I'm thinking of making the smallest possible mo...

Cam, The splashwell looks a bit on the small side for a V6 outboard to fully tilt out of the water, are you giving up that ability to conserve deck space for the livewell? also another dumb question because I'm sure you've thought this out, I don't see scuppers on the transom, how are you handling t...

ktm_2000

looking good Cam!!!!

whenever you get a chance, can you post a pic of your motor well?

ktm_2000

no pics on this one but I ground down the excess glass and used the left over filler from my transom work to put a first pass on the joints.

ktm_2000

I also started to make the bulkheads which will go around my fuel tank. I left them tall as I will probably be putting 3/4" meranti on top of the stringers to match the height of the original deck which I left around the perimeter. the back of the fuel tank panel was the first one I layed up in 5+ y...

I got the 1/2 of the transom core glued in today, while test fitting both pieces I noticed that I couldn't easily get at the gap around the perimeter of the first board.

I will have to try your technique with the filler. I originally intended of putting a layer of 1.5oz mat on top but I did not think that I filled the trough I put in to join the 2 pieces well enough and thought that I'd need a blast of filler or more layers of glass to make flat so I didn't add the ...

yes, I have a door on the port side right after the back brace of the radar arch.

Is my memory wrong on this one?

Cam, Your boat is looking amazing. The curved detail where you merge in the non skid to the top cap looks real nice. One of the things I love most about the bertram is the chrome detail on the bow, the bow chock is a work of art Did you have any of the chrome re-done? my bow vents are starting to pe...

sorry about your dog.

I love the way the 31 sits in the water on the wide angle shot with your dog on the transom, but the drone shot while on a slight turn is the real winner to me.

Hi Cam, On my boat, I just painted the flared out section another color, it doesn't stick out that much against the black bottom paint so I doubt it has any real effect on how the boat looks.

Did some more grinding last night and cut out that section. Once I cut around the perimeter the piece lifted off with no prying.
