Steam of exhaust while wakesurfing

[etang789]

I have a 2010 Nautique 210 Team Edition with Coastal Edition and 6.0L ZR-409

Recently I have noticed that when the boat is weighted down for waksurfing there is a lot of steam coming out of the exhaust, so much steam that it blocks the surfers view of the wake. However, the engine coolant temp stays normal.

Also noticed while I clean the boat after a day in the water, with the fresh water flush, there less water coming out of the exhaust.

I have just did coolant flush, since the coolant started to look really dirty. So I changed from the original Dexcool to Toyota Red Coolant.

We had similar issues, get a FAE never look back.

I was going to get one but I thought no one makes them as an aftermarket add on anymore.

However I am thinking to replace the raw water impeller first to see if the problem is solved.

I feel its mostly steam ,my g23 does that, sometimes I feel its a combination between water temp and air temp that causes steam so thick you can't see the wake...then a different time and day all clear and forget about getting a FAE
