It's all plumbed correctly but I believe a Beta 43 is supposed to be 43HP? 43/4 = 11sq ft of skin (tank). Nope, more like 8 at a guesstimate, I'll measure up next time. Whether it has any baffles is anyone's guess. The outlets are curved steel pipe welded to the tank so no chance of feeling for baffles with a bent coathanger or whatever. The "spare" skin tank has short stubs (cut off by the looks), but not drilled through the tank.

That is about par for the course ..... I don't have vast experience with canal boats but most of the ones I have ever worked on had insufficient cooling.
It's what killed a hell of a lot of the old BMC installations

I can't see the frothy little prop stressing the engine much TBH so I'll suck it and see for now. If it doesn't have enough cooling I have a MAHOOSIVE head start with the unused second skin tank. Musn't grumble.

The "spare" skin tank has short stubs (cut off by the looks), but not drilled through the tank. The skin tank itself must cover 1 sq. ft. of shell plating for every 4 bhp the engine is capable of producing, and should include one horizontal baffle plate at half height with the inlet and outlet connections at the same end of the tank. I would be inclined to make that fixed flooring above the skin tanks removeable, . . not necessarily loose and instantly liftable, but even if it meant a few minutes work with a spanner and/or a screwdriver to get it out of the way, the access would be so much better for routine maintenance jobs like belt adjustment or replacement. Also if your boat carries any stern trim the skin tank air venting plug, or possibly plugs, you're thinking of installing need to be positioned at the forard ends of tanks. I over estimated. 3ft x 1.75ft = 5.25sq ft. Almost exactly half your recommendation ...and there sits the second tank, unused. That's naughty but could be far worse. There aren't many hours on the engine and there is the second tank fitted. Series or parallel? The shell is well made, I'm going to guess there is a horizontal baffle. If there isn't, having inlet snd outlet at the same end would be a tragedy. And yes, up with the floor, there is also an upstand built permanently on the floor rising up to the engine cover/floor. Trad stern. More half-arsed boat fitting on the cheap.

Maybe you could check for baffles by looking for weld distortion and tapping it with a small hammer. I know there are calculations about skin tank sizing but there is one way to find out Deep enough section of canal with nobody moored, give it some oil and see what happens . And don't blame me if it all goes tits up.

Have you scrubbed the weed off the outside of the skin tank ?

Maybe the second tank was intended for a built in diesel genny.

The boat was built for the engine but some barsteward then only connected one skin tank. I'm sure it's fine for pottering about but it needs sorting. A tap to clean the threads, a few fittings and some hose is all ot needs, not too bad? I'll poke a stick down through the top fitting and feel for the baffle next time I'm in the vicinity. 👍
