Something for my Dockbuster

Postby mercaholic » Mon Nov 27, 2017 12:59 am

I have been seeking a light weight boat for my Mk78.

Found this one on Kijji.  The Owner indicated that it has sat unused for 8 years.  

It has what I think is an early '80's Merc500 that turns over and had no rat nests under the wrap.... icon_thumbup.gif.    It was used for water skiing so has the standard three blade prop but was told it topped out at 32 mph.  The hull and transom seem solid so will buy it tomorrow.  It was manufactured by a company called Neptune located a few miles from where I reside but no info on the company comes up on Google.  I've asked a few guys about it  here in our local AOMC Chapter too.

There is no longer the original Coast Guard rating plate but the Owner tells me it is rated for 90hp....huh... :roll:    

I think this thing weighs only 200# without the motor and is 13.5 ft in length, so how is a rating like that possible ?

More pics forthcoming once I get this thing home....

Interesting boat, looks like it may have been a clone of a Checkmate MX14.  What's the hull look like? Chines and pad if any.  With the boats like this we run, if it floats with the engine, that's my horsepower rating.  That thing, I think your engine will be ok.  I don't know how fast you want to go, but power trim and a jackplate would be a must for me personally.  Cool mixture though, 50s engine on 70s boat

That looks like the checkmate v mate I had, it was 15' and rated for 90hp and had a 115 on it.

I got the boat home and spent the day freeing up the steering cable and dismounting the engine.

Pics of transom indicate an interesting hull design.

I also measured things and the boat is actually only 13 ft so that 90hp rating is interesting.

I have yet to trace the engine serial number too.

Cripes!  Looks like my old hull. Hope it works a lot better.

It will because the bottom don't run down hill like yours does. This type of boat rides high at bow. agree it looks like a old checkmate or copy of one. A 90 will be a hand full i think.

Hull is close to checkmate, however this has a square pad, where a checkmate has a delta pad.  How wide is the pad?  Square pad boats handle better and ride on the pad higher, if you have enough power and prop to fly it.  That boat to me looks like it had potential to be a competitor back in the old FE days, before Delta's really took over.  
Gotta remember that 90hp max back then, was only 90 at the flywheel.  Handful for some I guess

I had a 14' Checkmate with a 85 4 cyl. on it. With me alone and a one 6 gallon tank just about empty, I could get 54 out of it if the wind was right. Your hull looks a lot like the one I had.

Did I miss something?  I thought this was a Dockbuster project, or do you consider the KG-9 a dockbuster as well?

Nope, you didn't miss anything.

I just planted that motor on there to see if things lined up on the transom as I may switch it over for one of next years' Wet Meets in these parts.

The Dockbuster proposed is as shown.

Poor thing needs a new home since the Ranger got sold.

Very cool boat BTW
