Re: 90 TLDI TPS adjustment ?
Then going back to your original question, "was this a mechanical or electrical issue", is...Dealer install error. Anything other than a factory propeller is always something of a crap shoot. Some are designed to work across a very broad range of engine model types and have a less than perfect fit. Hence you can get a little chatter with one brand and a little less with another. It shouldn't hurt anything other than your ears, but here's some free advice. You don't need a 4-blade prop on that engine. Four bladed props are great if you bought some 4-stroke wimp outboard that doesn't have hole shot, but it's a gimick when used on the average 2-stroke. Just drop down to the next lowest pitch on a factory prop for better hole shot. The engine does not come with a pre selected prop. Your dealer received whatever pitch they asked for when they ordered the engine. Prop selection is trial and error so you need to select your prop based on what you have now and what you are trying to achieve.
