This very subject has been debated on the forum ad infinitum in recent months without, it must be said, a definitive answer.

You don't mention whether 2 or 4-stroke. 4m Searider transom is rated to 110kgs and maximum of 50hp, although Dave Manning has owned 4m Seariders with a 70hp, but when you live in Wolverhampton, hey you need as much excitement as you can get. He'd be the one to talk to, or Rogue Wave, another Searider afficionado.

I understand the main issue with too much power on the 4m is the risk of chine-walking, although again there are those on the forum who'll tell you this isn't necessarily a problem. However, Steve at Fineway Leisure in Norfolk, an Avon premier dealer who sells shedloads of Seariders and is well respected, reckons the Mariner 40hp EFi is the ideal engine for the 4m boat and that even the 50hp is a bit over the top.

By the way the Mariner 2 stroke 60hp weighs around 100kgs and 4-stroke 60hp EFi weighs 112kgs. Let the debate begin..........

I've heard talk about strenghtening the transom to take a bigger heavier engine, having come out of the thick end of a complete transom rebuild i wouldn't recommend to to anyone.

Things to rememebr are:

Weight to power ratio.
Increased fuel comsumption.
Weight on transom.
Boat insurance.
Cost of engine against depreciation. - (can you sell on an over speced boat etc ?)
Chine walking and associated effects.
And will it make the boat handle any better in rough weather ?

Do a forum search on chine-walking using the Search button on the toolbar above - again it's been much discussed, but basically means when boat rocks from side to side at speed and becomes unstable and in extreme cases and if uncorrected can ultimately lead to a barrel roll! The result of the hull exceeding the limits it was designed for through the application of too much power.
