hydra 240 hv and neu 1515 good combo?

Sure but ya gotta do yer own brown nosing!...lol. And pay him an extra 135.00. My boat is sitting on his workbench ready to ship to me he's just waiting for my decal kit to show up then I'm set I should be running it in a week or so...when I asked him how well the 1515/1y performed on 5s he just made this evil sounding giggle.

Being a boat guy myself, you will not have any issue with an xl motor in a boat. Water cooling will easily handle any heat generated by the feigao. A neu 1515 will make more power, but in a 29" boat may be overkill. I run a modded spuervee 27" with the stock motor and esc. It does 43mph so far, and I can get 15min runtimes with a 7200 4s lipo (pair of 3600 for balance purposes), and no heat on anything. 12000mah 5s will get you better runtimes, but you will want to keep motor rpm around 30k. Most sport boat prop recomendations are based on around 30k rpm max. I run an octura x642 prop, and it hauls ass. The sv27 motor/esc combo is good for around 550-600 watts. If you want to go faster than 40mph (which is moving, especially with a sub 35" boat) you may want to go with a bigger hull, or find some glass smooth water. At 43mph, the trim tabs and half of the prop is all that touches the water on my sv27, you can see dailight under the entire hull. Boats are very fun, especially the pucker factor when you laungh, or submarine one. Best advice I can give you is tape the hatch with good masking tape...
