Hi all

So I recently bought a 79 Sea Nymph Gullwing (I believe) 5m.
Thing is that it came with a buggered outboard. Mercury 115hp, in pieces. I believe the motor has been deemed irreparable.

So,,,, I need to re power this sucker. But looking at pics from when it was running, it seems to sit pretty low in the water with the 115 and the aux mounted. Will a 70 HP suffice, or do I need to go for a 90/100/115HP?



I'm on a tight budget so cost is an consideration, but with that said I would be looking at as new a motor with as few hours as possible. I would also like to run as economical as possible.

Do I look at a 2 or 4 stroke? Not looking to stir up a hornets nest, but I believe that the 4 stokes are a bit more reliable?

Would it be worth mounting the batteries in the bow, it the cabin to push the nose down a bit?

I'm not experienced in boating at all, so any and all advice will be greatly appreciated.

Cheers

Thanks for the quick reply..
Te highest I would realistically be able to go is around $5 - $6000, and that is with a bit of a push...

I would probably look for a good used Yamaha 90 2 stroke on that hull and budget. The SWS Yamaha 2 strokes are generally very reliable (as good as the equivalent 4 strokes I reckon), but the SWS 115 for some reason seems to be very thirsty (well documented in these forums). 

Four strokes aren't necessarily more reliable. 

Yam 90 HP seems a good option.  I was quoted $12,000 each for new ones installed earlier this year.  So you should be able to pick one up 2nd hand close to your budget price

I suggest not storing your batteries near the bow.  They will get shaken around a lot up there, which isn't good for them - even marine batteries.

Yep I agree. A 90hp 2-stroke would work well for your boat and your budget. You may want to check out the 90hp Mercury as an option as well.  I’ve had both the Yamaha and Mercury 90 – the Yamaha was a little bit more refined, but the Mercury had the power.
