Volvo Duo Prop Propellers

However, that loss is more than made up by the duo props and the optimal drive angle afforded by the drive trim shaft drives lose power as their thrust is directed downwards due to the shaft angle. If you're not interested in top end, I'm sure you could change the props to get the better hole shot. Lets take a single prop of a given pitch and diameter. Anyway, the word weird came up here a couple times regarding the 226 so I figgured I would throw this in. It does squat the 7000 lb. While I'm at it, would anyone argue in favor of a single big block with a bravo3 dual prop over say twin 5. My own boat, which I bought secondhand, does not have counter rotating props.

I don't particularly care about speed anymore. Glad you made your choice but I do believe the Bravo 2 might fit your needs and save on repairs if it ever needs repair. Would notice more performance and handling improvements with a Duoprop. It may be the case that there is essentially a straight through coupling when in forward, and a gear set or extra idler gear engaged when in reverse. As you will appreciate with gasoline increasing at an alarming rate, anything to cut fuel bills will help. Order your duo prop today and save hundreds to thousands. This is where I got my prop.

February 12, 2013 Just a few short years after Volvo-Penta introduced the , its competitor Mercury Marine quickly followed suit and introduced stern drives of their own. The 260 and 300 are also supercharged as well as turbocharged. If you want simplicity and moderate maintenance, go with inboards. I'm glad they put the Raptor on a SuperCrew configuration, I'll be taking a look in a year or two. Really wished I could have jumped into the 5.

Duo prop vs Big single prop

Our cookie policy Ok yes 1. But is it worth the added cost up front and on the back side of the purchase? This reduction increases both fuel efficiency and speed. You can get close to stuff very quickly and can bump into things harder than you would like. Two propellers rotating in opposite directions -- the normal rotation for dual-prop boats -- cancel out the forces that pull your boat's stern away from a straight line. Drag and weight are reduced with the single powerplant.

As for handling, I have single Duo-prop on my boat. Not a huge deal, but I agree, why isn't it there? Did you ever try a four blade or five blade prop? Switching to synthetic gear oil doesn't help. I've got the torque to kill the launch issues and the thing will still do 50 mph. We are open 24-7 365 days of the year. At the bigger end of the scale and truly targeted at the 8m+ market is the D6 range, based on a 5. By going astern with the port engine and with full port helm the boat lifts off the pontoon sideways or starboard engine and starboard helm. You'll find most everything you will need that fits under your waterline.

Choosing MerCruiser Bravo 1, 2, 3 and Alpha One Boat Outdrives

Always use type C stainless steel propellers in engines exceeding 240 hp or capable of speeds above 38 knots 45 mph. I'm loving the truck more and more every day. The cost of maintaining the drive is the same, but prop trouble is double if you happen to booger up both of them. I don't know if there is a cost to do this when buying a new boat. For a 9k 26' 300+ prop hp.

Diesel Sterndrive Buyers Guide

It was little unsettling at first as this was the first time I've been behind the helm of a large bowrider. He's not trying to make money on selling you a different drive. As one of the leading manufacturers of sterndrives, MerCruiser brands by Mercury Marine offer very popular choices for inboard outboard power boats. By continuing, we assume that you accept such use. But what happens on straight inboards? But hey, it was impressive! For a high perfomance boat go with a Bravo One.

Cobra Conversion

Cons: more expensive to buy, very expensive to repair after a shoal impact, a lot more weight past the transom. I'll start with what I have been led to believe. Diane is also the author of the children's book. You will notice that response when backing into a slip in much faster. Trailered boats weren't as susceptible. Special features are akin in every detail, to the D-Series engines. Do not mix J-Series with A or B series on the same drive.

I've also run a twin engine Duo-prop and it seems to me that there's a difference in backing down and turning the boat using engines only. Twin inboards with outboard turning props left hand on port and right hand on starboard are the ultimate in close quarter handling. Part wise and mechanic wise, merc's may be cheaper in the long run. I'm not sure this is important because I rarely run much faster than 40, and generally cruise around 30 when not pulling a tube, boarder or skier. At 28-30 feet, your friend's boat will be in the water all the time I presume. The two props are mounted in front of one another and turn in opposite directions eliminating wasted energy from the propeller wash. In looking at dozens of makes only SeaRay offers a twin inboard v-drive actually option.
