Grumman 15 ft Sportboat

The man working on my pier left this boat at my house. I went out on it started to leak pretty fast. I brought it b ack to my house and found a pretty big hole. Im gonna patch it with sheet metal and rivets. The previous owner had done one patch before i got it. I plan on stripping the paint. I also plan on adding a front deck please leave suggestions

Wow, that patch must have been done by an aircraft sheetmetal mechanic; that thing is nice! I once flew in a Grumman sea plane, all Aluminium construction and it had side opening cargo hold hatches; pretty cool old bird.

Some 5200 a piece of aluminum and some pop rivets and she will be water tight in no time.

Ive stripped thepaint and im about to patch it. Im trying to find an engine.

Try to find a Evinrude or Johnson 4hp Deluxe. They are great engines.

Oh I forgot to mention that the Grumman 15 sportboat is a very nice boat for small lakes and rivers. They can take a beating. I beliece they are made with a 6000 series heat treated aluminum.

I live on the chesapeake bay and it handles fine their. Idont fish freshwater.

The only thing I would recommend to check out is the floation is up to date. I think the older Grumman 15 sportboats were concidered a canoe and I know floation is not enough to handle lots of weight when swamped. The newer years have updated floation.

I changed out the old foam in the bow and in the rear seat

geozigla · Jul 6, 2010

by the way does anyone know the year of the boat

hwew · Jul 6, 2010

The newer years also have foam on starboad and port sides.
Much more foam.

i guess mines old because there are no foam their

Try to contact Marathon Boat Group.

They should be some help. If you have a serial # to give them it should help getting some weight specs.

Here is the link.

Your welcome,

Let me know what you found out.

I always loved the 15 sport. A matter of fact I almost purchased one about 13 years ago.

You never know, I might get one someday.

i was only born 13 yrs ago

hwew · Jul 6, 2010

Well I think you are doing pretty good.
Please be safe and learn good boating practice.

i was looking at the boat and there was an area that was unpainted i believe that was side flotation that the previous owner removed

hwew · Jul 6, 2010

Get in touch with the manufacture and give them the serial #.
They should be able to tell you if it had side floatation.
