Quicksilver 380hd new engine weight

Hello everyone!

I own a Quicksilver aa380HD3n inflatable (owners manual can be found here: http://download.brunswick-marine.com...e/801875_5.pdf ).
Specifications: max engine: 25 hp / 60 kg. I want to buy a new 25 hp engine, but the lightest available is the evinrude e-tec, which weighs 66 kg. Should I go for it? I could use any experience you might have on what could go wrong with being 6 kgs overweight.

***I am trying not to buy any used 2-stroke outboard. I know they are much lighter but I would like a new engine.

Quicksilver 380hd new engine weight

Still marginally overweight but the new Suzuki DF25a has a claimed weight of 62kg - short shaft/manual start.
The DF20a weighs in at a svelte 44kg and both have the benefit of EFI.

Hi.. Im sure everyone will have different ideas..including yourself

But I don't think 6kg overweight would make much difference to the transom. However it would to you carrying it.

If it were me..I think I would consider a Honda 20hp instead..simply because it weights 46kg... and that would make a big difference to me carrying it.

Would a 25 hp weighting 66 kg be more beneficial to you over a 20hp at 46 kg ?

I run a 4.3 quicksilver HD with a 25hp two stroke and it planes very easy with that engine.. If I had to replace it with a 4 stroke.. I would go for the 46kg engine any day (My two stroke weights 52kg)

But that's based on my back..not the transom

I should add that as well as the 52kg 25HP two stroke on my transom..I also carry a 13kg aux engine.. I have no problem with my set up..so Im sure the 66kg engine wont do any harm

Your model is just 430 HD or is it 430 HD XS? Cause XS models got higher specs for maximum engine weight (based on the official manuals).

Hi again..I think XS means it is a Hypalon model..mine is just the PVC model.

reading my manual .. (mine is a 1996 model).. 430hd is max 85kg weight ...430hd xs is 85kg and the 380hd is max 71kg as is the 380hd xs

Perhaps they changed spec..as my manual clearly says the keel should be inflated to 2.5 ..while someone else said its written on their keel that the pressure should be 4.5 ?

I don't think tolerances are that important if reasonably close ?

Mine is 2001. At the time even the 430 HD had 60kg max weight.
Anyway I also don't think 6 kgs overweight will make such a difference. But I want to hear opinions. Could the engine perhaps submerge so much as to take in water while trying to plane? Thank you for your input!

I will also look into the Suzuki DF25a tomorrow...

Sorry..

I see you posted as I got my photos up.

Interesting that yours is 2001 ..some folk on this site keep saying the glue on PVC falls apart at 10 years..so its good to know yours is still on the go.

I also have another PVC boat that is around 15 years old and its still well glued together..but thought I was an exception to the 10 year rule
