I/O (Sterndrive) Conversion to Outboards

[Pmt133]

Someone definitely asked if they could test fit them first.

I remember how much of a nightmare selling my 3.0l was.

 

[tpenfield]

Are they still available? Is the price negotiable? Would you consider $1000 for the pair?

It gets worse . . .

Would you sell just the engines? (no . . . they don't work without the controls and wiring)
I'm a Merc Tech, I know this stuff . . . (no you don't)
How many hours? What year? (the listing has all the info)
I just need the throttles . . . how much for those? (same price as the total package . . . . )
I pooped myself when I saw the price (boating is probably not for you, try to get a complete twin engine package for less)

Keep a log and update all at once so we can savor...

Sunday was a fun day . . . Patriots football . . . narrowly escaping defeat
We get there fairly ealry and have the pick of the tailgating spaces . . .

.

.

.
Today is back to business, but the weather might have its input on how much gets done . . .
.
I got some detailed dimensions and patterns off of the transom. I used paper to create a template for making the shapes. It seemed to work out OK.
.

.
There are 4 pieces that will make up the contact area of the extension pod: 3 pieces on the transom and 1 piece on the underside of the swim deck. I figured it was best to template the transom-mating pieces and the 'upper' piece can be made from measurements.

After some marking, cutting and 'truing' up the shapes, here is what I have to outline the pieces on the Coosa board.
.

.

.
These are the sides that will mate to the transom. I got to bang the rust off my geometry skills and figure out the bevel angles on the cuts. . . basically 12˚ and 60˚ from my previous measurements.

I also have treated the transom contact areas with paint remover . . . probably going to need to soak in for a couple of days.
.

.
My plan is to get as exact enough fit to the transom that when the extension pod gets mated to the transom, the adhesive used to seal the extension can be uniform thickness, not having any excessive gaps to fill.

 

[Scott Danforth]

I would grind the gel off where you want the adhesive

 

[redneck joe]

And im assuming you will be using bolts in addition to the glue?

 

[tpenfield]

And I'm assuming you will be using bolts in addition to the glue?

Yes . . . lots of bolts. The 'glue' is more of a water-tight sealant.

I'd totally default to the acme brand over elmers....

But Acme only seems to work on coyotes. Roadrunners are immune to it's effects.

Progress Update . . .

Lots of measuring and cutting today. I'm into 3 of the Coosa panels . . .
Here is what I've cut out so far (highlighted in orange).
.

.
The big top piece (upper right in the picture) took a while to get just right. The other pieces were not too bad . . . lots of figuring on the bevel cuts so things will go together nicely.

My plan it to assemble these 5 pieces and test fit them to the transom contact area. I'll need to provide allowance for the fiberglass thickness . . . got to figure out what would be a good approach.

 

[tpenfield]

Some how, I managed to cut one of the pieces wrong. So, I got to practice glassing the Coosa board.
.

.
All set . . . don't do it again

[redneck joe]

And not rush and forget safety protocols. Didnt see any bone and flesh is gluing back together this morning and bandage change

 

[tpenfield]

Yup, it was one of those things . . . asked myself should I cut out one more piece and call it a day . . . Doh

 

[tpenfield]

In other news . . .

I have the 4 'transom mating' pieces secured to the transom with a about a 3/32" 'spacer' all around to mimic the fiberglass thickness. (Pics to follow in the AM.)

Temperatures barely hit 60˚F today . . . more like 57˚F. I am having to tent the work area after the glass layup and apply heat. Much of the fabrication/glassing will be done in the garage, which can be heated to about 68˚F. For the stuff that has to be done outside, I'll have to figure out a better method of tent + heat. Right now, I'm using 2% MEKP and kicking the resin with a heat gun in some cases.

 

[redneck joe]

Gonna be 75 here, no wind and bluebird skies. Im off to drown some worms.

 

[Scott Danforth]

Its 84 here

You could probably preheat the resin in a warm bath to help too... Starting with uncatalyzed resin at 75-80 degrees may help?
