A cheaper , faster , way of keeping water out of your boat is learning how to use the throttle . Replacing a splash guard I can understand but adding one ...... do you have to drill holes ? Keep in mind , when water does hit it , is it goin to set in the seam and then creep into your boat anyways . I've even seen people go so far as to put a bead of silicon around it . We all know how good some people are with silicon on jet boats .

Just keep in mind that in a jet boat there will always be water in it . The pump is designed to have a drip of water coming in to lubricate it . YOU WILL ALWAYS HAVE WATER IN YOUR BOAT . There is no way around it . Besides , if I'm not mistaken , bilge pumps are cheaper that the guards as well . Think it through . Just hate to see some unessicary holes drilled which arent really solving any problems.
