If you're interested, I put together a quick thread on our latest vacation to Lake Ouachita and our first extended use of our restored Tige, here:
https://www.tigeowners.com/forum/gen...-it-s-worth-it
Only had two real issues with the boat during the entire week. One is living without the center display, which prevents me from getting the speed control module rebuilt (no way to set the speed). Any suggestions (Tige tech support has helped me a bunch, but we're at a standstill) would be greatly appreciated.
The second is a few minor details concerning the engine. First off, there's a large dead-band (maybe 40+ degrees?) of throttle movement between forward gear engaging and any increase in engine power. Is there any way to adjust the throttle sensor to get rid of that dead-band? I'm thinking "No", because adjustment in the forward direction will affect the rear direction as well. Not a big issue, but was a surprise.
Second detail is more interesting. Engine start up, warm up, idle out to no wake zone is fine. Moderate throttle movement, where the rpm reasonably follows the throttle movement (after the dead band), is smooth and normal. But an aggressive movement, like pulling a skier up, will result in one or two backfires as the engine accelerates from idle, then smooths out and runs normally.
I had experienced this earlier on a test run, and tried retarding the timing (turning the distributor clockwise) a small amount, but it had little to no effect.
So, I wonder if this problem is fuel related. Could the injectors need to be replaced or rebuilt? As I mentioned, it runs fine once it gets past this initial transition, so none are clogged. But I wonder if the spray patterns are compromised.
Or could it be octane-related? I've been running the same fuel I've always run in my '96 La Brisa (5.8l PCM, carbureted), and both engines have essentially the same compression ratio.
Thanks in advance for any ideas, and have a good one,
Mike
