52" Sports Yacht deep V... only labels I could find are included in the photos (found on the front of the hull)...After exhaustive searches I found a few boats from the manufacturer but not a single photo or mention of this boat Replaced the carb and got lucky as heck literally visually guessing on a replacement carb...couldn't find markings even after disassembly of the original carb...no markings anywhere on the motor...nothing under the housing, pull start assembly..nowhere...only thing I haven't removed is the exhaust assembly...I got her purring like a kitten..so really not wanting to guess at a new gasket.or lean on rtv...😆...original dual rudder assembly was broken so I replaced with semi comparably specced rudders and rigged a new linkage setup to get her turning....turns like a dream..ordered new motor mount (rubber shock absorbers anyway) as the originals are less than desirable...lol...looks like hot glue wa used to keep them in place...all in all I've got about $65 invested...(randomly guessed at a prop without any engine specs and she's getting on plane but only getting about 35mph out of her...still need to fill some breaks in the gel coat...but after that I'm planning to experiment with 3 blade props...diff sizes/pitch etc for the speeds she was intended to run..but for the sake of time and money I'm hoping someone might shed some light on it (especially the motor) it'd be nice to have a starting point based off the original spec prop, engine specs etc...its my first 2 cycle ever...other than a nitro Miss Vegas I've only ever run fast electrics (regarding boats)...so this is exciting and the run times are mind blowing to me and all very very new..but this trial and error craps starting to wear on me...lol

my inquiry is regarding the white v hull at the bottom of the frame

threw the cover on the motor just for visual reference of what it looked like originally before my troubleshooting

visual reference of motor hoping someone might help identify it

Photo showing the name of the manufacturer and the only other visible marking

ps...haven't had time to research it but it appears the cooling runs from under the hull..runs through a manual pump then through the head but there's no outlet...would I be correct in assuming on gassers (this one specifically) the water exits through the exhaust? All my nitros and electrics have water outlets but nothing visible here...so I leaned on critical thinking and monitored the temps and she looks good... lol...again wore out on researching...said hell with the risk...I needed to see it run..😂

Homelite strimmer engine ?

Honda red is more....red.

Petrol so a water cooled exhaust a good idea, water into exhaust low down and away from exhaust port.

You say cooling water scoop on hull bottom, usually close to prop....

Any indication on fuel tank ?

You may have to measure for cc....

I'm not an expert, not by any stretch of the imagination. That being said, the engine and hull both look like Chinese manufacture. A quality US made gas boat won't have a bottom water pick up, route the exhaust out to side of the boat or dump the water through the exhaust. You will see a water pick up, if not two, machined into the rudder blade(s) and the dump being a dedicated fitting through the side of the boat. As far as water cooled exhaust, the quality ones almost always have a header going into a tuned pipe with an integral "O" ring sealed water jacket going around the header. The tuned pipe will almost always be routed through or over the transom for safety as well. Those that use a canister style exhaust, quite often a stock Zenoah for example, will usually have it's outlet(s) pointed up with nothing attached to them

Some of us, perhaps many of us, prefer to spend our hard earned dollars on gas and food than support US unions. And quality got going in Japan after Ford refused to spend the money on it.

Are you talking the Mazda 323 vs Ford Escort comparison back in the 1980s or 1990s? The quality edge went to the 323, much to Ford's dismay.
As far as supporting unions, I don't. I don't work for a union company and haven't in almost 30 years. When I did, the union dues I paid turn out to be wasted. When I needed the union's help, something I was supposedly paying for with my monthly dues, I was told I was on my own.
Let me make something clear on this. I've seen the quality of things coming from China and most of it isn't worth the cost of gas to go buy it. I'm supporting the small US companies like:

• Speedmaster
• Quickdraw
• BH Hanson
• Aeromarine
• Mack's Products

Granted, there's a lot more out there, the five I listed just came off the top of my head. I also stayed with companies that make boat parts. I could have included Desert Aircraft, Zenoah, Futaba and many more larger companies that make aviation parts, marine engines and radio gear.
