    Yes. Thank you.

    292 inline 6 with prealpha drive for 19.5 cuddy

    Enough with all the grinding and fibreglass dust… Tonight, I started laying new glass. Just the PB fillets to the stringers, but it’s nice to be building back rather than tearing out and grinding.

    292 inline 6 with prealpha drive for 19.5 cuddy

    Looking for feedback on my repair plan. I’ve nearly finished grinding out the delaminated/deleterious fibreglass. There was a layer of chopper glass which was about 1/2” thick. It was delaminated and in poor condition. In the process of grinding this out, I gouged into the hand laid layer of the...

    Thanks. There was a layer of loose chopped strand type glass that came up easily. I used a wire wheel on a drill which was quite effective. Found sound glass below which looked like the hand laid up hull. I have a few hours of grinding and cutting ahead of me before it’s ready to start glassing...

    Slowly progressing this repower project. The 292 is running and ready to be installed in the hull. I’m in the process of removing the old front engine mount and replacing with new side engine mounts. After removing the front engine mount, it seems I have a bit of a mess… There was a half inch...

    292 inline 6 with prealpha drive for 19.5 cuddy

    I have a spare thermostat housing and water pump which I could drill out and tap for 3/4” NPT. I’m a little nervous that it doesn’t leave much material around the outer edges which could cause either the pump or the thermostat housing to crack…

    And, any idea which thermostat housings would fit this motor and have a 1” outlet? I’ve been trying to find something like your sketch, but have not had any luck.

    Ok. Great info. Thanks for the sketches. You mention an 18” long HX, however the one I have is 27” long. Subtracting ~3” for the ends I’m left with ~24” tube length. Can I proportion your calculation up: 24/18 X 350 = 465Hp, meaning the HX would be suitable for 230HP motor + 230HP from exhaust...

    Opened up the manifold. It looks to me like the rust is still pretty superficial. If the HX can support full cooling, I think it would be worth cleaning out the manifold to allow for a full FWC system. Is there a calculator or table I could use to assess the HX size?

    Seems like the obvious answer here is to run with a half FWC system and just replace the manifold when the time comes…

    I ran electrolytic rust removal on the block. Not sure how well it removes rust within the block, but like I say, the block was not in bad shape (nothing like a raw water cooled marine block).

    The exchanger may be a little crusty, but I recall it being in decent shape… I’m planning to remove the end caps to rotate the water inlets orientation, so I’ll get a better view then. The block was from a wood chipper which ran coolant. It was in good shape and I DIY ‘boiled’ it out…

    I believe it’s aluminum.

    Yes, just a flow through. Two 1 1/2” ports.
