Don’t know what this is

If the hull is around 54" long it looks like a Dumas Scarab 38 KV. The engine may be a Homelite,either 25cc or 30cc.Looks simular to one I had.Mine didn't have an arch on it. It broke.Do you have any idea of the manufacturer of the outdrive ? It may be worth more than the boat.

I see you have a stick radio under the boat. If it isn't one made for surface (75 mhz or 2.4ghz ) put it away and get a pistol radio.The old AM radios are not desirable for use these days.

A hatch would be hard to find,but Warehouse Hobbies used to have a hatch mold for the Scarab.Warehouse is https://enforcerrcboats.com/index.php?route=common/home and is owned by Bonzi Sports https://www.bonzisports.com/
Give them a call or email and see if they still have the hatch mold. I believe it was made so you wouldn't have to cut a hole in the hatch floor to use a gas engine. Here's a pic of the original hatch on the one I sold.https://cimg8.ibsrv.net/gimg/www.rcu...b19c5821c8.jpg

Someday when you're ready to upgrade it and do some real work,here's a build thread on one on Jim's r/c boat dock. Jim's R/C Boat Dock

The only problem with that link is it won't get you into the site unless you're a member

It's free to join and they have a good sales or wanted section,plus other sections that may be useful in building gassers or just wanting advice.

I understand that, but you have to remember that some don't want to join a forum just to see a picture. When you consider that I already belong to two forums, why should I be forced to join a third?

I belong to nine r/c boating sites and several r/c airplane sites. Several are electric and nitro,but also offer a place to post about gas power.I was never forced to join any of them and each has given me info that I needed and with great pictures. As they say a picture is worth a thousand words.The link I provided to Jims is not just pics ,it is a build thread to show how to improve the Dumas Scarab 38 KV and push it to it's limits. Another valuable site is Model Gas Boats www.modelgasboats.com which has how to articles and tech on just about anything boat related.Some sites you can get on without registering,but you can't post or ask questions and basicly you're just a lurker.I'm 70 yrs old and like pictures. I can understand written words better if there's pictures with them.
