How much fuel does a classic V8 really burn ??? 1989 350 Mercruiser tested in a 23-foot Scarab

[@antonrehling1966]

I had a 26 foot Bayliner with a 350 inboard, I never cared or thought about how much fuel per hour I burned. I just had a crap load of fun.

[@Hitech82]

I have a Bayliner Ceira 2355 It has a Mercruiser 5.7 210hp 2 barrell carb. Alpha1 this boat with fishing gear and fuel tank of gas 55gals. weighs in at 6000lbs. I trolled 27miles over 9hours and burned 14gals of regular gas. The next day we ran off shore and back 37miles out and back. Mostly running 3200rpm. Burned 18 gals of regular gas.

For those interested, that's 2.738 MPG, converting liters to gallons and nautical miles to standard miles.

personally didnt buy my powerboat for fuel economy... its what we enjoy dont matter the cost

I have a 1990 Bayliner Trophy Hardtop 2459. Engine 5.7 magnum Mercruiser, Alpha 1 drive. I cruise at 3350-3400rpm, speed approx. 22 mph, fully loaded (6000+) fuel, water, food for 4 days out overnights. Burn roughly 8 GPH depending on sea conditions. I plan on a burn of 10 gph for safety margins. Travel time to fishing 3.750 hours each way here in Alaska. Had my boat since 2008. Propeller plays a big factor my friends. Turning Point Voyager SS 14"x15" propeller.

Large carb v6 outboards burn a lot of fuel. Having personally had ski boats with both. Bullet 1800 powered by a early carb 175hp Mercury 2 litre power head and then a Camero Volante powered by a 350 chev. The 350 used little more than half the fuel of the outboard over a typical weekend of skiing.

And no two-stroke oil to buy

My 89 Baja 190 sport 5liter 1885 lbs has a 20 gallon tank .

[@jacobkelley519]

About 2.5 to 3 miles per gallon is what i get. Thats in a 1994 ski west california skier. Doing about 10 to 25mph.

Loving your channel TJ, I have a soft spot for all these great boats of yesteryear. I pick up a 1994 Haines Signature 470df going to waste in a neighbours yard last year, it was great to bring it back to life again. Keep up the great work. 😊👍

[@tjmarine7121]

Thanks for the encouragement mate. More videos coming soon.

[@AquaMarine1000]

Diesel sterndrive is the way to go.

[@rogerboeing]

i always compare fuel to a weekend at a good hotel my 28 searay will burn $400 on a good trip 80 klms a hotel near the water over a grand....you do the maths

[@uncle_salty_3675]

I have a 88 seaswirl with a omc and 350 sbc and its not bad on fuel just driving around but skiing or tubing or anythjng and it really sucks it down lolol

[@damienjohnson7582]

Mate that is a great video. I’ve seen you out there.

[@Paulsmarinesalvage]

A mercruiser 228 is 305 cu/in not 350. Also, that is not a scarab model.

[@tjmarine7121]

They were built here under licence in Australia, I know not the same as the proper American ones. Are they not based on the 350 chev small block? I'm fairly certain they are.

[@Paulsmarinesalvage]

@@tjmarine7121 no, that engine is small block Chevy based however it's 305 cubic inches. Different bore, different head chamber, different valve size. It's a lower horsepower cousin but not a 350.

[@tjmarine7121]

Interesting mate I didn't know that. Thanks.

[@randie450]

I'm a bit confused here, is it a 5.7L or a 5.0L Mercruiser? If it's a 5.7L it would be based on a 350 chev sb.

[@Paulsmarinesalvage]

@@randie450 the engine in the video is a Mercruiser 228 which was a 5.0/305 cu small block Chevy. Though the video says 5.7 that's incorrect.

[@davesboatingfishing]

If you need to ask that question 😁, then sell the boat. But a good video otherwise

[@tjmarine7121]

haha it's out of interest more than affordability but as it happens she is for sale.

[@scott5747]

What a waste of time.
