webbing on quick silver

can anyone tell me if it ok to cut the webbing on my quicksilver 310, i mean the fabric either side of the outboard which i guess is to stop splash back, i have some new transom wheels and wont fit without cutting this a little.i have very little time before my trip abroad to return them and get the ones which swing out, any advice appreciated

Hello..
If your engine meets factory min & max height specs regarding anticav plate to sib's bottom height, there is no need to use side webbings, as no water splash will occur. Put trim angle to second hole from transom, place weight towards middle of boat and make a wot test in flat waters, if there is no visible splash sign, then procede to cut, it's useless. What is your brand engine and rated HP ?

Mariner 9.9 same as 15 HP could be a disguissed Yamaha or Tohatsu and both have different heights factory recommendations.

If it were a disguised Tohatsu (shaft acceleration ) the parameters are 30 to 50 mm, if it were a Yamaha (cable acceleration) the parameters are 0 to 25 mm. Both have different exhaust forms, angles, legs. Using a measurement tape measure your actual height bottom transom to anticav plate height, see if inside parameters. Are we talking about a short shaft engine ?

Test on calm waters and see for yourself, if no water splash then cut. Some boats have them as pure cosmetic issues, but will depend entirely on sib's transoms heights, 38 cm ones will splash specially with Tohatsu, Mariner, Mercury, Nissan engines. 40 cm or higher will not splash a drop. Sib's transom has been raised to 40.5 cm from previous 38 cm height. Now performing at it's best, no water splash and fantastic top end speed.
