SR4.7 with Mariner 60hp EFI Bigfoot

Hi guys - does anyone know what the top speed of my Searider 4.7 is likley to be once I repower it with a 2007 Mariner 60hp 4-Stroke EFI Bigfoot i recently picked up will be (assuming its just with me abord).

The reason I'm asking is my insurance company want to know before they confirm the premium.

Also - does anyone else have this same setup who could advise me on what prop i should be fitting for good allround performance?

Many thanks!

Did you get lucky and buy the orange one on B&O?

I reckon it will do around 33 - 35 ish, as for the prop you will have to see what the revs are at top speed.

Prop wise, i would guess at about 15" pitch. The MoD 4.7 seariders with 60hp 2 strokes use 17" pitch, but the four stroke revs out to 6000rpm so should be about 15" ish.

Ok thanks chaps. No - i didn't buy the orange one, i bought my 4.7 about a year ago. The orange SR at Retreat Boatyard looks really well looked after - can't tell if it is a 4.7 or an overpowered 4m - looks too big for that though? I may swing by next week or so and take a quick look as its only a couple of miles away for me.

I'd say you'd need a 17" pitch prop with a 60 EFi Bigfoot.

Top speed will be around 32-33kt

And the 4.7 loves to cruise around that speed
