HI :)
I am a proud and extremely satisfied owner of a 1994 Mariah Shabah 211 boat (The model is identical to the 212 shabah but in Europe it was closed bow and was named 211 ) powered by a Volvo Penta 5.0 Fi /Duo Prop engine { Crankshaft power 235 hp Propeller shaft power 220 hp Engine Weight 930 lb } with F7 stainless steel props .The acceleration was great (I use it quite often for water skiing) and the top speed ( 2 pax and half tank) 55Mph at 4600 rpm (top for Volvo.)
Unfortunately after 14 years the engine died .:mad:
I want to re-power the boat with a Mercruiser 5.0 mpi 260 hp Bravo 3 Engine Weight 1019 lb
My questions are
1) I want the Bravo 3 option but other boaters say that the bravo 3 is not suitable for my boat :confused:because it is to long and weigh more than the Alfa 1 and is not going to give better acceleration or cruising speed (the Volvo duo prop was great)
What is your opinion .
2) I was thinking to install an swimming platform to my boat. How is the extra weight going to affect the performance (Ski towing ski wake Planing and cruising speed)

Sorry to hear your engine died!:(

In order to change to a Bravo outdrive, you need to change out the entire transom assembly as well, as a Bravo drive will not fit on an Alpha or Volvo transom assembly. That is a big expence and really not needed unless you are putting an engine in that is above 300HP.

If it were me, I would simply put in a replacement Alpha engine. Much simpler and much cheaper.;)

Not sure where you are located, but I happen to have a 250HP 5.7 for sale, if you are interested.

Thanks,

Hi DVoutsas,

300sflyer is correct, is quite a large undertaking to change over to a Bravo 3 setup so if your outdrive is still in good shape, just re-power your Mariah. From what you posted, you seemed quite happy with your original setup and as they say, why mess with a good thing.

See if 300sflyer's 5.7 will bolt up with your Volvo Duo Prop outdrive. The extra HP and torque will probably make your Shabah feel like a whole new boat :wink_thumbup:.

Good luck,
WetWilly

:)Hi guys
Thanks for your replies. Unfortunately I don’t live in USA I live in GREECE and the shipping for the engine is around 2000 usd .I have already sold the old transom assembly so I am looking for the complete package (engine and transom).
The difference in price between the Alfa And the Bravo complete package is very small.(Maybe our Merc dealer went crazy :yes_grin:)
WetWilly Yes I was quite happy with my original set-up which was a duo prop outdrive ad this is why I want the Bravo 3 (I am a duo prop addict) but I don’t know the differences in performance between the Volvo and the Merc drive(they say that the Bravo 3 is only for big boats )
Waiting for your replies :eek_animated:
