Hi all, first time poster here. Thanks for any help in advance. As posted, have a 2003 Suzuki DF70. Up until this year have loved the engine. Now having to do some work on it to keep her going but that is to be expected of a 4 year old engine that stays in the water. I have a problem that perhaps you all can help with. This last weekend while pulling my wife wakeboarding the engine was very sluggish, as if someone had an anchor attached to the boat. Engine was very slow to get to 4000 RPM and then it was would stay there for a while and then all of a sudden would jump to full throttle. It felt as if a turbo charger kicked in and then the boat would run beautifully. If I had to start again the same problem would occur. It does NOT happen all the time but about 3/4 of the time. The only recent thing done to the engine was the 100 hour maintence which I did myself and included all new fuel filters, a control cable adjustment for a lower unit that would not get fully into gear (now fixed) and the addition of a Sierra Water fuel Seperator which was added because of possible bad gas issue. Idles beautifully, on the hose seems to rev up fine, but under load really sluggish. Any thoughts????
