Performance of F350 vs. Verado 300 on the 32

[hydra-shortz]

Just was interested in the 32 and wanted to hear about the Verado 300s vs. the Yamaha F350. Cruise, wot, fuel economy, handling. Wonder if the new Yamaha F300 V-6 will be "too light" for this boat, etc. Anyone with real world info would be great. Having both livewells full, is there too much weight with the F350s?

Also, i would be doing a lot of slow trolling. Would the pitch of the props on the F350 make the boat go too fast for slow trolling? I will be attending the Miami Boat Show to really look at this boat hard. Thanks for the help.

I'd be very interested in these numbers too.

Yamaha (F350) website: "Weight* 25" shaft / 804 lb ; 30" shaft / 822 lb "

Mercury V300 website: Weight (lbs / kg) 635 / 288

Theres also a current F300 from yamaha that weighs the same and is a V8
is this "new" F300V6 in the works or something?

Yamaha offers the new 4.2-liter Offshore F-series outboards rated at 225, 250 and 300 horsepower. Each has a dry weight (no oil or prop) of 558 pounds with a 25-inch shaft, or 51 pounds less than the previous-generation 3.4-liter Offshore V6 models, and a very significant 246 pounds less than the previous Offshore F300, which used the 5.3-liter V8 powerhead and was simply too heavy for most applications in the 300-hp range. For comparison, the Mercury Verado 300 weighs 635 pounds, and the 4.0-liter Suzuki DF300 weighs 580 pounds. You could still go lighter with a two-stroke, however. The Evinrude E-TEC 300 weighs just 528 pounds and remains the lightest regular-production motor that rating. The Mercury OptiMax 250 weighs just 505 pounds. The weight of the two-strokes also does not include a prop or the oil reservoir and oil.

All New Powerhead


The new 4.2-liter Yamaha Offshore outboards offer 24 percent more displacement than the 3.4-liter V6 models they replace, yet weigh 51 pounds less than the previous Offshore V6.
The 4.2-liter powerhead is all-new but will still be familiar to Yamaha fans. With a 60-degree cylinder angle, double over-head cams, and the exhaust ports facing each other (Yamaha’s “in bank” exhaust arrangement) the basic layout is the same as previous Yamaha V6 four-strokes. Electro-mechanical variable cam timing on the intake side is offered at all three power ratings. It’s the same system previously used on the Offshore 250. That feature combines with a larger, 75mm throttle body and longer, retuned intake runners to significantly boost low-to-mid-range torque, according to Yamaha. Full-throttle rpm range is 5000-6000, with peak power rated at 5500 rpm. The 225 is happy on 87 octane fuel, while the 250 and 300 will make peak power on 89 octane, though they will run on 87.

Perhaps the key technical highlight of the new powerhead is the sleeve-less cylinder design that replaces typical steel liners within each aluminum cylinder bore. An alloy dust of chrome, nickel, manganese and other elements is super-heated in a plasma process and fused to the cylinder. This saves about 6.2 pounds of weight and permits about 2mm more cylinder bore in the same block size. The coating is said to be 60 percent harder than steel and thus very wear resistant. It also offers a “micro-texture” surface (think about the dimples on a golf ball) that holds oil to further reduce wear, aid cooling, and significantly reduce friction, which in turn enhances both power and economy. This texture is really micro. To the naked eye the surface looks smooth as chrome.

Further weight reduction was achieved through careful casting techniques and little things like trimming excess steel from the camshafts and using new plastic cam covers. Overall the 4.2-liter powerhead weighs 17 pounds less than the 3.4-liter V6 it replaces. A new composite lower pan (the bodywork directly below the cowl) replaces the previous aluminum pan and saves 12.7 pounds. The mid-section was re-shaped to cut 11 pounds. The alternator weighs 5.6 pounds less.

One livelwell full, full coffin box, drink box full of provisions 2000k lbs crew and gear, 325gal fuel low 60's on the top end 1.25mpg@40 with stock yam 23p wheels.

I had a set of verados on a previous boat and do not miss them. Put 200hrs on the 350's this past season and aside from regular maintenance didn't have the cowlings off. Couldn't be happier with the Yam 350's on the 32.
