thanks for the advice, that what i wanted to hear. anyone have any other good questions?

how about this 60hp eng. what input do you guys have on that?

If you are looking at outboards 5years old or less consider that:

Tohatsu TLDI (direct injection 2 stroke) 40 & 50 hp outboards are 205 lbs

Suzuki 40 hp, 50 hp & 60 hp outboards are all the same weight at 229 lbs.

Honda 40 & 50 hps are about 214 lbs, their 60 hp is about 242 llbs

ETEC 40hp, 50hp & 60 hp are also about 240 lbs

Yamaha 50hp, 60 hp & 70 hp are about 251 lbs

Above weights don't include the tiller arms (which you'd want for this type of boat)

To me it would make sense to go with the most powerful engine you can at a given weight. The US navy use specialized 55 hp ETECs on F-470s with the Durajet drives which brings their weight to 262 lbs. So you should be fine with any of the above 60 hp outboards with regard to weight and power.

I'm familiar with these numbers because I've been researching for my own 4.7 meter inflatable. I currently have a ~1995 Yamaha 40 hp 2 stroke (about 180 lbs) which has been bombproof but is fuel thirsty. This fuel thirst does limit my range between re-fueling (I often take 5 x 5 gallon jerry cans of gas on trips, and don't want to have to haul any more than that). Personally, I'm finding the Suzuki DF60 to be the most appealing of the bunch.

super info, thanks for the advices. the more the better guys, keep it coming.

right now im about 85% buying a 60hp. is there anything bad about having a 60hp? what the con's beside the gas.

If you are comparing fuel consumption of a 60hp outboard to that of a 40 hp outboard of the same make (eg Suzuki DF60a vs DF40a or an ETEC 60hp vs ETEC 40 hp), you should see pretty much the same rate of fuel consumption at outputs of 40 hp and under. The main difference will be in the tuning and that the upper rev limit will be higher on the 60 hp.

In other words, if operating a 60 hp engine at the same rpm as the upper rpm limit of it's 40 hp counterpart (or lower) you shouldn't see a difference in fuel consumpiton. Same engine displacement at the same rpms should result in the same fuel consumption.

Now if you spend the vast majority of your cruising time with the throttle pinned (as I like to do ), then yes, you will burn through more fuel with a 60, and have a whole lot more fun doing it!

ok good info, im at 90% now towards a 60hp. I havent told the seller what outboard I'm running yet. he said that if im running the 60hp he will drell holes into the transit board so I can mount the 60hp with nuts and bolts so it will be better reinforce.

I also just got a 18 gallon zodiec bladder for $250 from the seller. is that a good deal?

As Peter said. That boat will only accommodate 40hp. As far as I am aware you can't just put an Ali floor in any sib. They are either inflatable floor, or rigid. Meaning that sib is designed to accommodate up to a 40hp motor with the Ali floor it comes with. A 65 is way way overboard. It will weigh too much, possibly break the transom and invalidate your insurance. If I were you I'd be getting a rib all day long.

I dont get it, when I was in the marines in 2004 I was traind on a Jonson 55hp and I was using it with the FC 470. I know for a fact that Johnson 55 was way heavier than the evenrude. whats the difference now with the FC 470?

I could be wrong but that's my understanding of that transom plate. And it may appear the 60hp is no heavier than a 40. That's still a lot of power on an inflatable boat!

Assuming the boat is capable of handling the 60hp the only problem then is the ID plate. It is illegal to go over passenger amount, load weight, or horse power. That is a Coast Guard plate and what both the insurance company and Coast Guard will go by. Unfortunately it can not be changed either as it has the boats ID number. Removal of it is also illegal for a few reasons which I am sure you can figure out.

The only reason I am familiar with all this is that I know people who owned 6 passenger boats but always put more people in. The sheriff or Coast Guard on the Sacramento Delta and surrounding lakes would use the plate to determine if they were within the boat specs or not. So yes under the right circumstances the ID plate might be examined.

Again for what you want to do I would HIGHLY recommend a RIB. I have driven right next to my friends 16' Zodiac RIB and while I was getting beat up he was riding smooth in the rough water. Should I even mention how a slightly larger RIB does in rough water? I would bet buying a complete used package will cost you about the same. Tworotorturbo is trying to sell/trade his Zodiac.
California: Anyone want to trade their Avon 5.4 Searider for my 2002 Zodiac SRMN 600?
