2550 Walkaround 454 with Volvo outdrive...What is the outdrive model?

Riverman · Postby **Riverman** » Sun Apr 28, 2019 9:48 am

We just joined the 2550 club!!

To get her ready we need a few pieces for the outdrive, but we have no idea of the model or gear ratio.

We are in saltwater so as you can imagine no data plat!

Ours is a 1992 with the 454 horizon.

Anybody have a model or serial number that will get us close for parts?

Thanks everyone!!

It would also be super helpful if you know what the gear ratio is and what props and speed you get!!!

Start with pursuit. They may have record of drive serial or should at least know what ratio they originally installed. They are very responsive to emails on customer support

You are right! Holy cow they where fast. No model numbe, but they did have the gear ratio!

Prop shop should be able to get you in the ball park if you know current wot weight of the boat engine hp and current prop diameter and pitch

As far as the parts that may be a little mor difficult.

Mercruiser or Volvo? If it’s a horizon engine I’m guessing that’s a Merc outdrive...in which case I’m not helpful in any way haha.
My ‘89 2350 walkaround has a Volvo DP-A 1.95 ratio
