Mounting new outboard

mattiasb · 19 December 2003, 12:53

Hi,

Like to use the knowledge and expertice of the forum. I've just up/down graded from my Johnson V6 175 hp -97, to a new Suzuki DF 140 2004. I'm looking for tips/sites/thoughts on how to mount it the best way and what to observe. I noticed when the other outboard was lifted of tha it wasn't centered - is ther a good reason for that? Any knowlede i propulsion or cavitation outthere?

Boatmake: Osprey Seaharrier.

Very grateful for any info in subject.

Hi Mattias;

It`s not in the center because you compensate the rotation of the prop by moving the engine a little bit to the side, how much they install the engine on the side depends on what kind of engine and what kind of model of boat.

Here is a pic were you can se that engine is a little bit to the side.
It`s a Osprey Seaharrier Max, same boat as you have but 80cm longer.

I can see why but is there a list/schedule in wich u can out read how much to either side it should be mounted in regards to engine and boat specs?

Regards
Matt

PS Trims needed on the Max version?

Only experience

All depends on size and type of boat and size of engine.
Bigger the hp the more offset.

Which side depend on which way the prop spins.

Thers been a few thread recently talking about this do a seach on it.

Things it depends on-

Prop Spin (normally only 1 way apart from counter rotation).

HP

Hull

There is normally a chart hp/offset in your manual for you hull. would imagine it would be 20mm to starboard, if your holes are centered and they fit the new engine try it as is.
