Ecotec Motor going into a boat

[4bait]

Started getting the Ecotec ready for a transplant into a boat it will still be a little way off as I'm waitng for a new sterndrive thats coming from the states and don't want to take the boat out of action until the colder months, so just starting to get things Ready.

heres a few Pics of the water cooled manifolds taking shape

Pay no attention to the dirty motor as it is yet to be stripped and overhauled.
I got the series 2 engine for $30 because the previous owner thought it was no good and didn't know what was wrong with it, but all that was wrong was a broken $20 valve spring.

Heres the manifold pics under construction built out of 316 stainless.

plasma Cut out the exhuast flanges

Drilled out the stud holes using the original manifolds as a template

bent up the angles needed and welded inplace whilst still bolted to the block to ensure the risers sat where I wanted them and to try and minimise warpage.

Heres one manifold almost finished just got to fit the anaodes and the water inlet tube and polish it up.

when finished they should look something like these ones that cost $2500
at least if mine don't work, I know I can buy them pre Fabbed Can also get some Cast Alloy ones From NZ for around 2K if need be.

these are the Alloy NZ ones that look real nice, there fitted to the same motor with a super charger and it delivers 300 plus HP, but I think the stainless will be longer lasting.
The Super charger may still be an option down the track.

This is the boat it will be going into

This is a cool project. Keep the pics and info coming

thanks Guys

will keep the updates coming but this project will still take a couple months as I want to keep the boat going while the fishing season is still good, Also the new outdrive is coming via sea so it will be 4 to 6 weeks before it arives. Grrrrrrr

Next job will be to cut and shut the sump and build adjustable engine mounts then rebuild the motor to make it nice and fresh.

Cheers Andy

Nice work mate, no messing around with your bate, ey? Most people are happy with a 20hp motor, much less a 200hp motor.

Sometimes I think thats where my motor belongs, on a boat, at the end of a very long chain.

The second exhaust manifold is nearly finished.

.

Also got the front engine mounts done.

Made them out of Alloy, as I want to try and keep weight to a minimum.

They are fully adjustable up and down so I can Line the drive shaft up properly. They will bolt up to the stringers.

Next problem is that the oil filter sticks out too far to fit between the stingers so I need to decide whether to cut some stringer out of the boat and glass it up again for clearance, or whether to fit a remote filter.

Cheers Andy
