Yeah 3.8 not the shit 3.6
Or vq30

The VQ had crossed my mind.

VQ25DE suitable? Slightly lower power maybe a better match. probably the same weight and mostly the same parts as the VQ30DE. Good thing with the Nissans is the imports seem to rust out so are pretty cheap to buy.

Diesel?

Got a jet boat in the shed with a 3.8 buick, good power and simple/reliable.

I would suggest choosing a motor renound for high mileage/reliability. Unfortunately this generally means old inefficient heavy slugs.
Marine engines have a pretty hard life compared to the same engine mounted in a vehicle,there is no coasting or downhill just constant load.
Also not usually the option to walk home.....

I am not up with the play on modern engines enough to recommend anything but will say make sure it is well powered,always better economy/safety to have power in reserve.

Some vehicles really lend themselves to adding a different motor. Put a 1uzfe in an e30 once, man BMW made it easy in a lot of ways. Engine loom is completely separate, and battery lives in boot, so could push it in and out of shop into rain and still wind the windows up. Speedo was driven off the rear end, so no pissing around there. Only major issue was clearing the brake master and booster, which we solved with a Renault Cleo booster (same stud pattern) and a D21 Isuzu master (right everything else, and 1" vs 7/8"). Made all the headers and twin 2 1/4" exhaust from scratch. Went like the proverbial raped ape. Wasn't mine (boss's) but was insured as the courtesy car so several customers got home with a sweat on (no we didn't pick housewives for this treatment)

Also, a lot of engines are getting hard to come by. If you want just a bit of pep but plenty of spare engine availability (cos they might get drowned) a 1ZZ corolla motor would be the go.

Also, what size boat are you pushing, and what sort of budget?

Im not pushing it!(maby toward the trailer when he gets it going?)

Time for a photo of the heart transplant recipient I think @gadgetman

A short, heavy, fat fibreglass 17'/5.3m Vistacraft from about '71-'73 with a Volvo Penta stern leg. Was used commercially out of the sounds. Original B30 170HP engine was overhauled about 5 hours ago, but has been sitting a few years. I'm picking this should be run with lead substitute additive.

Highest priority is reliability. Will always be used with a 5HP aux. Not sure on budget, want to do most of the work myself.

See if I can find the photos on the PC. Was on Photobucket till that turned to custard.

A dunnydoor V6 would be a good powerplant. Can pick them up cheap.
Lots of marine bits available as jetboaters love them (or used to).
Plenty of options to use either carbs (like speedway guys run) or full EFI with std ecu and simple wiring harnesses available as well.

She's an ugly duck but the hull is in excellent condition.
