osprey splash over transom query

hi out with me osprey eagle today and every time I stopped there was water sloshing around the transom so while underway I looked around and I have a lot of water spraying up around the tube cones and up the transom . on one side the top of the transom has like a lip that directs the water backwards but on the starboard side the lip has been cut away to allow an aux outboard and the waters piling over there. is this just a trait of the osprey and something ill have to live with or is there possibly something else wrong .the boat seems to ride great otherwise straight and true .the outboards a contra rotation offset the correct amount but I cant see how that would cause this, a friend out with me said he thought I had quite a rooster tail going on

What do you have hanging off the transom... any transducers. Is the aux clear of the water when you are running at speed. ?

RIBase
Sounds like outboard might need lifted, very similar to what I first had. I lifted mine up 2 holes which stopped the rooster tail and associated splashing over the transom. On my Viper the transom lip is still intact on the stbd side but I removed part on the port side for an aux outboard. No water comes over at all anymore. Trial and error as most RIB / engine / weight set ups are all slightly different.

thanks there is no aux fitted at the moment there is a small transducer but its on the starboard side and it splashes both sides. the outboard has already been lifted as there is a gap of about 30mm between transom top and the outboard saddle and im not sure how much higher it can go without having to alter the transom

With the engine trimmed fully in (down) Where is the engines Vent plate (or cav plate) in relation to the bottom of the transom. Can you take a picture of the back of your boat at prop level so we can see ?

ok so I finally managed to get some pics and its looking like my outboards to low but its already mounted high on the transom if I lift it more to get the cav plate level I'm going to have the saddle two and a half inches above the transom top pics to follow when I manage to upload them

that wouldn't bother me in the slightest....put a 2.5" bit of wood under it if it bothers you or glass it in if it really bothers you.

my own engine is probably similar (bit less maybe to be fair) above the transom if it makes you feel any better

it does thanks. to get it at the correct height i am going to have to lift it the last 2 holes then thats it it cant go any higher without drilling new holes in the transom.i wonder if this outboard has an extra long leg but to be fair its running like a swiss watch at the moment so im quite keen to keep it and the rib apart from the splash is driving great
