That looks like my old boat called ffodos. It was exactly the same as the Bond boat although it didn't have the horn on the front when I had it.
I blew up the original engine so bought an old Olds with a 455 (330 bhp)in it and did a swop. Then the fuel pump failed so used an E Type Jag one that worked a treat.
It sounded amazing with only rubber flaps over the exhaust outlets. Really inneficiant Berkley Jet though, massive rooster but not much speed considering the power. Got some photo's somewhere, if I find them I'll try and post them.
It was sooo heavy,I reversed down a ramp once, braked and with all wheels locked up I carried on sliding down until the boat reached the water.
