Mercruiser Alpha (1) vs. Bravo III Choosing the Outdrive

When Mercruiser powered you often a choice the single Alpha I twin prop III outdrives. best choice on a of factors engine horsepower, type, boating and personal In this we cover pros and of each and the to consider on our of both over the

The Similarities

getting into differences, first ll consider similarities between two drives:



Similar Transom Trim System, Ring, Steering and Trim

Use of Mercathode anti-corrosion (standard on III, optional Alpha I)

vs. Twin The Alpha uses a aluminum or steel propeller propulsion. Advantages a single are:

Increased speed vs twin prop to reduced

Lower replacement

Easy to propellers to acceleration (water vs top (cruising) as

Less complex in lower

The Bravo use twin propellers made stainless steel motive force. of the design include:


Straighter at all due to cancellation

Better of horsepower water (especially 260hp) for same prop

Outdrive vs. Mounted Raw-Water A major of the I is outdrive mounted pump. Servicing pump requires the lower-unit the outdrive. is fairly to do land, but in the It also a full of outdrive and is messy. The III uses pully driven mounted on engine. Depending your engine servicing can be a but at you don have to with gear or handling awkward lower

Dog Clutch Cone Clutch Alpha I a dog design for The dog is known its reliability, not for finesse. Alpha go in out of with a clunk . drives use cone clutch offers smoother that is a touch distinctive to Either way, difference is aesthetic and a big on performance.

The Alpha a lightweight to the III. A Alpha weighs 75lbs where Bravo III props is to 200.

Twin stainless propellers on aluminum outdrive special challenges corrosion protection. III s a bad for early due to The net-lore overstates its but we any Bravo owner pay attention to mercathode system anodes. It also true most Alpha are on boats whereas Bravo III a large of the express crusier under 40 length. All outdrives, be Mercruiser, Volvo, OMC are for wet-slipped

Choosing Between

There are application areas we feel choice is for either Alpha I the Bravo

Single Engine 22 and == Alpha due to weight. For size/powered vessel, weight penalty the Bravo will likely any gain low-end acceleration. 20 Chaparral with 205HP the Alpha could top at close 50MPH with 3-blade prop still plane in under seconds. If planing was for skiers, could swap in under minutes with single wrench.

Engine over == Bravo due to coupling. In case of performance boat, might also looking at Bravo II max speed, for most you ll better performance the RPM and much handling with

Most Twin Express Cruisers Bravo III better acceleration. is less than the 2 rules, generally speaking express cruisers out a easier with Bravo III. the weight horsepower ratio this becomes more important. Regal 2760 an extreme weighing in to 10,000lbs but powered the basic Mercruiser 4.3L Early versions the boat with Alpha and can problems getting plane, Bravo versions have had problems though the III is normally used this little

2) Speed: My is faster matter what load is. think the reason is the Bravo allows me get almost of he out of water whereas boat plows at maximun 3) I perfect pass when I 6 people the boat 3500 rmp speed is .2 mph than having people.

4) I pay $1800 again? definitely. To my 3551# Ray is a different league with Bravo III top speed, and ability keep similiar at each with a or full aboard. I wouldn t another boat a single unless it a Bravo going forward.

I wish could have something on internet with comparison when purchase my Lucky for I wanted Pewter color Select and only one could find in another and my choice was Bravo III I purchased in late 2006. Prior my purchase thought I wasting money my boat only 20ft heavy) and I wrong! feel free email me my email because few have two boat to the Alpha to the III and d be to answer else s on whether should buy
