Cal 29 outboard conversion

Also, just wanted to check before I cut, do I need to do any type reinforcement of the transom other then to support the engine? Concerned if the part I'm cutting provides any type of structural integrity to the boat? Thanks again for the help. JoeCal 29 Sent from Yahoo Mail on Android

Hi, Joe. If there is a Cal 25 (flat deck) around, it might be good to check to see how that transom is done. There is a laminate beam between the cockpit and stern fiberglass to provide structure (curved about an inch along a 3 foot length). Also, you could measure the height above the water for the cutout. If you are using an extra-long shaft (25 inch) engine, then you would want your cut about 5 inches higher than the Cal 25. Can’t go too low because you might be washing into the cockpit on following seas. I’ve made several of these beams (thickness based on space between the interior and exterior glass). I will say that the installation is not trivial due to space limitations. I have some photos of the process on a Cal 25 if you are interested. BTW, the cut-out piece serves as a stern plate when you remove the engine. Apparently, these were done with template after the boat was put together. On Cal 25s, no two were alike.

Pics would be great. My plan was to cut about 2-3" in from the curve where the transom goes from thick to thin. Would this put me past that structure you mentioned? Also, plan on cutting about 15" above the drain hole, so the outboard will clear the rudder. It is a mercury long shaft, so just a bit more that 20" from bracket to cavitation plate. Going to install a sealed wood backing on the cockpit side of the transom and put a stainless piece of where the motor will clamp, with two stainless bolts running through all of it. Thoughts?

Just sharing, our formerly owned cal 29 came to us with an outboard bracket (hard to lift up when sailing). We kept it on for a while after we revived the A4. It was offset on the port side a bit on the uncut transom and the bolts came through to cockpit side, which had a large stainless plate as a backing, and inside behind the lazarette. It was an old mount that lifted, would be close and out of the water and when in use and dropped, would stand out and easily clear the rudder. When we pulled the bracket, we could have put the ladder there, but never did. I then filled the holes, touched up with gel coat and polished. I would never cut up the transom, but I would be sure not to weaken, and maybe reinforce while in project mode, for the backstay chainplates. The 29's cockpit drain works pretty good, but a drop in the rim could be hairy in a following sea with some wind. I think you should pick up one of those back flow stoppers to screw on the outside of that drain hole. Before I put one on, the ob motor or the A4 prop digs in, not like sailing where your stern rides level or high. Then you stand in water as it gushes in. Sorry I've been on our 36 spreader project, but hope you rethink this, I feel strongly about chopping up these beautiful boats. We helped a friend in halfmoonbay install a 9.9 longshaft on the centerline of his engineless 29 using our old mount and it cleared the rudder. One more note, when sailing, the outboard prop is a real drag , at least a knot.

Before we got her, my brother-in-law had cut the transom of our 29 which we've since restored. If you look closely to the cut transom in this photo (http://summerwindsailing.com/transom-restoration-base/) you'll see some blocks glassed to give the wooden trim (removed at this point) something to be mounted (screwed) to. The wood you see laid at the bottom sits in about a quarter inch on top of what I remember as a structural piece. This photo (http://summerwindsailing.com/cut-out-transom/) shows the cut from behind. I'd guess it to be a little lower than what might be cut for an outboard. I never bothered to look or measure for an outboard as our intent was always to upgrade the diesel. That said, having had a cut transom on a 29 my advice would be to stiffen up the cut sections by adding material and then glassing it in; I'd want it to be solid. John Cal 29 #966

Joe, I like Helen' suggestion. For as little as $150 you can get the OB out of the water and keep the transom intact. http://www.defender.com/product.jsp?path=-1|215570|1825671|2348991&id=58033 Duane Duane Knize S/V Marlyn 1978 Cal 2-39 #18 berthed: Emeryville, CA kn… [at] san.rr.com On 4/9/2016 12:23 AM, Helen Horn he… [at] sbcglobal.net [Cal_Boats] wrote: > > Just sharing, our formerly owned cal 29 came to us with an outboard > bracket (hard to lift up when sailing).
