Possibly engine upgrade 40hp - 60hp

I have just heard back from Southern Pacific who say I can safely put a 60hp engine on my boat (currently fitted with a 40).

How much extra speed can I hope to achive with the extra 20hp? Is it worth upgrading?

Mate - your increasing the power by 50% so it'll fly

Only you can decide whether or not its worth it - how badly do you want to go faster? Also, think of the extra fuel consumption and that extra weight on the back end - may upset the balance slightly?

Is the upgrade a substantial investment or have you got a deal on a 60?

Could go the whole hog and upgrade the lot!!

One of those dilemmas!

Cheers

Yer it is a dilemma. I would love the extra speed, but then I have to weigh up the cost issues; I currently don't have a spare 3k for a 60.....Also with petrol getting even more expensive it might not be the wisest of ideas. But then, the extra speed.....................

It's nice to have dreams!

You can never have enough power I think the main thing to consider is that when you sell your boat eventually with the new engine, you would be unlikely to get the money back. From a financial point of view you would probably be better of selling yours as it is and spending the money buying something a bit bigger. Although a 60HP will be thirstier than your 40HP arguably you would'nt have to thrash it so much to cruise at a good speed. Well thats what I'd tell my parents!

Good luck,
I would estimate you would see a good 35 knots with a 60HP on your boat.

I wouldn't buy a new one; I'd therefor be looking at about 1800 for a half decent 60hp Mariner 2-stroke. I'd probably get about 1000 for my exisiting one. Mmm. Time for some contemplation......

How old and it what condition is your existing engine ?
Have you been actually told that your old engine is worth 1k ?

I changed up from a 50hp 2 stroke to a 60hp 4 stroke late last year, the increase in performace is measurable and the new engine uses half the fuel the 2 stroke did, now i can go a lot further faster for a lot less money......and as a bonus it's not having to be fixed every other week
