Thread subject: Whaler Central - Boston Whaler Boat Information and Photos :: Another Take on the Rage Conversion

Here is another interesting Rage outboard conversion.

Its powered by a 9.9 hp tiller motor - Im guessing strictly trolling speeds here - Its way too little HP and the motor looks pretty high up.

I guess it's safe to say, that boat is no where near over powered :)

LOL - that is true..... :D

Is he using that as a kicker? Hardto tell, but it looks like the jetdrive might still be in place? Thats a yamaha powered Rage i think, always thought they were worth keeping as-is. then again if you have the 9.9 laying around and the yammy motor pops, what the heck? lol

The engine may be in there - but I doubt it runs - Its for sale and is advertised like this...

"1992 14ft Boston-Whaler,with Yamaha 9.9 four -stroke electric start engine,shorelander trailer"

The original engine must not be working because the 9.9 is a tiller and the steering wheel was removed.

Good observation on the steering wheel not being there.

rage update
Well, I bought it, and here's what it looks like so far....
That's a longer shaft 9.9.....

Has anyone thought of filling the existing Rage transom with Nida-Bond http://www.nida-core.com/english/nidaprod_nidabond_transom.htm or Seacast from www.transomrepair.com as part of the conversion process?. I was looking at these as possiblities.

Andy,

I have known many people to have great success with nida core on many projects but I do not know of anyone who has used it for a rage conversion. I think the cost of the material vs. the amount needed is one of the factors for people choosing not to used it for the rage conversion.

Many have used the seacast product to raise the transom on classic 13's but I think you might have problems with it trying to fill a large void at the bottom of the transom instead of the top.

Thanks Jeff for the quick reply. I just thought it would allow for less fiberglass work and wood build up on the transom if I could re-enforce the existing transom by making in solid on the inside. Then the jack plate could mount directly. But as you indicated the cost would be higher.

Andy it really isn't that hard of a job to do it the way I did.

To hollow out the transom and fill it with seacast would be a considerable task - the foam in the transom is really in there and just wont come out - plus you would have to take the top area off somehow which in the end I think would be harder then just making a plug and glassing it in. Unless you are talking about just filling in the hole with it in which case I would think there would be no structural support at all. I think you really need to spread out and transfer the force of the outboard.

Thats just my .02 from someone who has already done it.

Thanks Scott, Since you have already completed this successfully, I guess I'll follow your lead.

Thanks for the offer Scott, I was looking at some of the construction photos you had posted on the net, but I'm not sure I understand exactly what was done on the transom exterior.

I've given this tutorial a few times before. No big deal. I will start with the usual disclaimer. It worked for me - doesn't mean it will work for everyone. I don't want to be responsible if something happens or doesn't happen or whatever. Anyway here is what I did.

Joe... if you want me to move this to a personal page let me know... sorry for the photobucket img links but I can figure out a way to narate and add pictures with the attach function unless I reply to the same thread over and over... Feel free to edit and move if you need to.

Before going any further I want to give credit to where credit is due. Bob Kemmler Jr. first converted this Rage before I did. He was the one who had the guts to do what every one said not to. A lot of the ideas were adaptations of what he had done. I wanted it fiberglassed in and thats why I changed it from the way he had it. Anyway thanks Bob!

I started out with a bare hull - no jet drive or anything.

First thing I did was create a 3/4" plug for the jet intake area. I made it so when I glassed it in it would extend through the transom and create a "shelf" for the wood I was going to add to the transom to sit on.
[IMG]http://img.photobucket.com/albums/v472/sraab928/Rage%20Conversion/pic22.jpg[/IMG]

Next step was to fabricate a plug for the transom to fill in the space. It was quite thick and to be honest I do not remember how many pieces of 3/4" I laminated together but here is what it looked like plugged.

Next step I took was to create stringers that would take any force from the plug and transfer it to the original hull area where the jet drive mounted.

Next I had to build up the outside of the transom to compensate for the natural lip. I do not have any progress pictures of that step but basically I took 2 pieces of 3/4 marine ply, laminated them together and then laminated them to the existing hull while resting on that extenstion I had from the jet drive plug. Then I covered that with one piece of 1/4" ply and one piece of 3/4" ply to carry my flat area above the natural ridge in the hull. Here is a pic of that.

Then of course lots of glassing and fairing and gelcoating....

[IMG]http://img.photobucket.com/albums/v472/sraab928/Rage%20Conversion/pic44.jpg[/IMG]

Then finally jackplate mounting and motor....
[IMG]http://img.photobucket.com/albums/v472/sraab928/Rage%20Conversion/DSC02921.jpg[/IMG]

There were plenty of pitfalls along the way. Like buying a jackplate with not enough setback. Going through two troublesome motors. A bad bicycle accident which resulted in shoulder surgery, rehab and lots of rest (while the boat was half done in the garage...). In the end I would do a project like this again in a heartbeat. It was a lot of fun. I learned alot about fiberglass and epoxy and myself.

Let me know if I can be of any assistance.

No problem.... if you get stuck shoot me an email or pm and I will give you my cell number... sometimes you just need to be talked off the bridge... :D

I forgot to add - I added an alum plate to the inside of the transom where the bolts came through to help displace the load. Here is a pic of the finished area.

Thanks Scott, I was just going to ask you if you laminated a plywood interior transom plate across the entire transom and to the interior sides of the boat to strengthen the overall transom....Andy

I put one 3/4" marine ply on the transom between those two up and down bumps in the glass on the transom. Then made an alum plate and 5200'd it in place.

Great conversion job. Been looking for a 15` Rage for a while now. If I could find one with a bad/no engine and a cheap price it would be mine. Bob Kemmler said his porpoised with an outboard. I don`t see why if it was set up rite.

I'm finishing up a conversion on a 14' Rage now. I used a lot of the ideas (and mistakes) from Scraab928. My plywood transom buiildup follows the slope of the top of the transom where Scraab928 followed the slope of the bottom and needed a shim. My builtup approximates the 15 degree (or so) slope of the average transom. I created a jack plate out of some 1/2" 6061 aluminum plate and angle iron bought at the local scrap yard. I designed it with a 10" setback. Should be enough. I got a 70 HP OMC outboard partly because I've always had good luck with OMC and partly because I could use a lot of the existing OMC stuff (controls, wiring, etc.). Obviously, all cables, wires had to be longer. I replaced the rack & pinion steering with a rotary that I found on ebay.

I've got a couple of weeks before water testing so I can't comment on that yet. I'll post pictures if anyone is interested.

Bob
