The seawater pump finally changed from an electric pump to a belt drive. The biggest problem was where to place it, in the end suitable and the only such place was found under the charger. To do that, I had to make a mounting piece that I bolted to the front mounting bracket of the engine. The attachment itself had to think for a moment about what it should look like. This is how it turned out:

The big holes come into the bolts of the clamping iron and there are two 8mm bolts in the slot that hold the pump in place and the pump belt can be tightened by pulling the pump outwards and by tightening the bolts it stays in place. In the slot, the bolts cannot rotate because its width is 13mm, which is the same as the 8mm bolt base.

The pump is under the charger, now I still have to hide those, maybe next year. The outgoing hose still needs to be pulled through a new route, but this is still a beta version of the implementation. There is no need to turn the hose from the front to the heat exchanger on the other side.
