Not able to plane

[collins1172]

I am having difficulty planing my boat. I have a 3.5 K&B. The boat is a top speed 2. At first i thought the fexshaft was coming in and out. But i dont think that anymore because as it cuts in the water starts flowing out of the head and as the engine cuts out the the water quits flowing. I noticed on a hard turn the boat stays running longer and also at lower speeds. But as it just starts to come over idle it cuts out. I have balance the model at 2 and 1/2 ounces on the front. Im strting to think i may need more weight. The manual states that you need 1 and 1/2 ounces to balance it but also states that when using k&b you will need to extend the engine out 3/4 of an inch. Which could cause why i am using more weight. Does anyone know whats going on with my boat? Brad :?

Hi Brad what prop are you using and how deep are you running it and what angle is the lower unit at. and is the engine rich enough
