Yep that's the same boat. I'm looking for a smaller boat that I can run on the river with the 75 merc that I just picked up. We don't do water sports and often have 4 people in the boat max. The PO of the tarantula ran an older 40hp rude but says it had a 60 on it at one point. I'm trying to dig up some info on this one to see if its worth the effort to put back together. I want something fun and fast like 50+ mph.

I grabbed an old trihull that has a nice running 96 75 merc on it with trailer for $800. So in theory I can rip all the goods out of the old trihull and put together a fun little rig. I want to be in the water for less than $2k.

I would probably look for an old Hydrostream V'king if I was you.

Try the guys at scream and fly or try fiberclassics. You do confuse me a bit: Do you intend to have more than one person in the boat? You do realize that it is a single person hull.

It may not be rated for more than a 40. Most of these small hulls were like that. On the other hand, if it were a class racer it will not have a capacity plate. If the length is less than 13 feet, certainly a 75 will be too much engine for it. The Coast Guard has an on-water test for determining the horsepower these mini hulls can carry. It involves a specified course. The boat is run through the course with varying horsepower engines until it can no longer make the turns. This is a very simplified explanation.

Go to youtube and search Frank Acampora videos. There are several of my 10 foot tunnel hull with both a 50 and a 60. The 60 was simply too much engine.

You probably will get close to 50 MPH but anything more and you will need to do some modifications like a jackplate and low water pick-up on the engine. You certainly will need to use custom props if you are serious about going fast.

Also understand that you have a very special hull: You must lean out well over the steering wheel to get it down and onto plane. You certainly don't want to run it in traffic. You ALWAYS want to WEAR your PFD. I have flipped my 10 foot tunnel three different times.

According to the owner the boat came with two back to back seats which he has stored in his shop to keep them out of the weather so seating for 4 was the way it came. It's from that time when crazy things were happening... This motor clocked 43mph on the trihull, you think 50mph is asking too much on a sleeker hull?

Is there anything to be cleaned from the tag? What does the DOT number mean?

I doubt you could get 4 people in that boat unless they were contortionist circus midgets. I dont even think you could get 2 in there. its 3' shorter and about 2' narrower than my buddies switzer craft super hugger (which can only fit 2 adults and 2 children - or 4 freakishly small people)

this is a 4-seat go-fast outboard boat http://www.kijiji.ca/v-powerboat-mo...ydrostream-canadian-edition-v-king/1090408575 or

regarding that small 13' boat, you could call your local AHJ and ask them what the DOT number means.

So I went and took a look at this thing yesterday.

The bad news is its nothing more than a fiberglass hull, it needs everything. Transom is totally rotten but it looks like the easiest transom repair in history, the original transom wood is exposed plywood on the inside that is just glued to the fiberglass hull. So no grinding etc to get it out just replace and glass in a new piece. The two halves of the hull will need to be separated but that looks pretty easy, they are just pop riveted together and I would expect to have the top apart in half an hour. Restoration would be very simple. Also there is no flotation foam anywhere in the boat, so if I wanted to add some I'm not sure how I would make it work...

The good news is that there is no separate floor there are 4 pieces of 2x4 glassed onto the hull where the back to back seats were mounted and that's it. And yes I think you could fit 4 people in there but it would be tight, the gas tank is under the nose so the cockpit area is pretty much open, If i did build it, I think I would just build it as a 2 seater this time. Maybe even a bench with a little storage area behind for all the gear.

Here is my question, as mentioned above I have a 96 75 merc that needs a home, would it work with this hull? I can't see anything on the boat that says what the max power is and I know that it at one time had a 40hp on it. I'm assuming it was rated for 600lbs of people since the 4 seats. The tag is really faded but it looks like the rated weight is 3XX KG of load weight which puts it at 700-800lbs. So If it was built for two people that total 500lbs with gear, would the 75hp be too heavy? Looking at the transom I think I would want to mount the motor on a jackplate to bring up the height because the transom height is only about 12" before the hull shape changes, the motor would be buried in the water otherwise.

If you like the boat go for it. It sounds like it wouldn't be too costly to repair. As for the weight of your motor you could float the boat and add weight equal to the weight of the motor and see how it floats.
