Engine Day

This weekend was a big step towards the completion of my "Rough '93 Ski" project. If you'd like to see what it is like to pull an engine from a 1993 Ski Nautique, have a look:

Gary,

OH!!!! Thank you for that observation. I didn't realize the normal process was to remove the bellhousing. I will do that as soon as I get home this afternoon.

The stand is a "backup" to the hoist at the moment. I'd say that 75% of the weight is still on the hoist and 25% is on the stand.

Kris - As I thought, the trailer is so bent that I was able to get it out by just lowering the front end down to the ground and having the windshield removed made it very easy to essentially just roll it out the front.

moon, if I knew anybody with a tow truck I would give that a try.

I imagine by now Kevin the neighbors will be happy that your almost done You have to start lining up the next project to keep them on their toes

The parts boat is ready for the dump. It was quite an afternoon:

Boat Chop-up

So let me get this right...

you have the fiberglass floor, then a layer of foam, then an aluminium frame, then foam again...
Or is the layer between the foam layers also fiberglass and just the thin vertical plate aluminium?

Other question... Would it be possible to do this setup on the older boats?

Kristof,

That aluminum plate is vertical at this point in the boat. Interestingly, it is a L-shape at some points where the engine mounts. The L is up-side-down and goes right under the floor. At this point it does appear that the fiberglass floor is double-walled with foam in-between for some reason. It is really hard to see, but there is a composite stringer in the midst of all that foam as well.

Tim - I suppose you could say I "kept" the in-floor cooler and battery box. I am keeping the lids as they are just carpeted pieces that nest into the holes in the floor. What do you mean by "trim"? They are basically just glassed into the boat floor.

See picture below: I have this section of the boat still as one complete, and very heavy, piece. This section was cut out from what is the front here back to the beginning of the engine compartment.



Good image of the composite structure in that picture too.

Looks pretty interesting.   I too wondered if this could be done in the older boats... seeing the design in section view makes me think it is possible.   if you used roger (uk79's) pour foam in a mold idea, you could basically make a foam stringer, then wrap your glass around that to the right thickness.   The question of cost is certainly a big one, that and time... I think Coosa might be stronger, and woudl be less labor time to make a similar final product.   the only way I thnk this method could be economically feasible is by the economy of scale... 30 hulls, you could make a template on the ground, and have the hull guys laying up their part while the structure guys were working separately...

Looks like the foam in the bow was cracked a long time, or do you think the tree did it?

Took a few more pictures, but will have to post them later.

Just for everybody's information the boat hull weighed 1,100 lbs (by the scale at the dump). That includes carpet, but the engine cradle was removed.
