In 2016, Briggs & Stratton released a new fuel injected version of the ‘big-block’ 35bhp engine that we use in our Marlin & Coastal-Pro hovercraft. Upgraded to 37bhp and with fuel injection, unfortunately, it was initially only available in the US market. We had to beg and plead with Basco (the UK importers) for some months before the US would give one up for us to test.

The motor has already proved popular with the ‘Mud Motor’ community so we had high hopes it would make a good hovercraft engine. When we did get our grubby mits on the first one in Europe, we ‘hoverised’ it and installed it into a Marlin ‘Beast,’ handing it straight over to no less than Jeremy Clarkson to open the ‘Clarkson, Hammond & May LIVE’ shows. When we got the craft back (reasonably undented, remarkably!) we got down to proper testing, putting another 50 or so hours on it with no issues whatsoever. Then we removed it and fitted it into a Coastal-Pro MACV where it has behaved impeccably for another 60 hours.

So what do we think?

Well, we love it to be honest!

Headline power figure is only 2bhp more than the regular, identical-but-carburettored V-Twin. However, it feels considerably stronger than that – and fan data seems to suggest that it could be nearer 40bhp than the advertised figure. Meanwhile, the improved torque of the engine is very apparent, with excellent throttle response and a higher resistance to ‘fan-stall’ when turning at high speed. Tickover is very smooth, and it appears to be slightly more economical, though that is more difficult to accurately quantify.

Since then, we’ve fitted eight to customer craft and they’ve performed really well.

Installed in the Marlin, it makes for a lively performer with excellent hump performance and injects some real sparkle into the craft. In a Coastal-Pro, the engine gives noticeably more push, which is great news when undertaking demanding work or with more load on board.

Price-wise, it’s a more expensive engine, so the premium is £450.00 compared to the standard 35bhp carburettor engine. Personally, I think it’s worth every penny – but it’ll depend on your own requirements and budget of course.
