V34 with Yanmar 3GM30F fuel consumption

I have just taken ownership of a 1998 Victoria 34 which has the original Yanmar 3GM30F. Are there any Victoria 34 owners out there that might be able to give me a rough idea of litres/hour fuel consumption at whatever rpm they tend to cruise at.

I know that it all depends on propsize and other things but any information would be helpful as currently I have no quick and easy way of measuring how much fuel is in the tank.

Thanks,

Adrian

Re: V34 with Yanmar 3GM30F fuel consumption

I can't actually measure my consumption either; I've got a basic air pressure monitoring setup that tells me if I'm full or not smile

Consumption should be around 3 litres per hour though if I remember right.

The service manual for the 3GM30F, page 26, has the consumption curves on a test bench.. https://victoriashadow.co.uk/wiki/index.php/Manuals

I presume you can't easily take off a cap on top and put a long wooden stick in? (I'd understand if not - Blue Opal's tanks are actually twin tanks in the starboard cockpit locker, and there's no inspection hatch.)

Re: V34 with Yanmar 3GM30F fuel consumption

Thanks for that Duncan. I'm in the same boat (!?) as you fuel tank wise, 2 connected  tanks with poor access and currently no way to even dipstick the tank. Hopefully I will get the tank tender working at some point but for the moment I'll keep track of the engine hours, have 30 litres backup in jerry cans and fill-up whenever I can.

Re: V34 with Yanmar 3GM30F fuel consumption

For what it is worth I reckon that my V34 with the same engine has a burn rate of about 1.5l /h. i have a fixed 3 blade prop and cruise at 2400 rpm which give 5.5 to 6 knots oner the ground most times I'm using the engine. I've owned Kaya for the past 17 years and find the fuel tank meter reasonably accurate but i normally carry 20 litres in a jerry can.

I own Blue Alligator, a Vic34 with the original Yanmar 3gm30f and a 3 blade featherstream prop. At around 2500 rpm the consumption is 1.5 l/hour.
