Have to do a long river run at 6 - 7 knots - about 1 hour - before I can open the throttle. Last time I opened the throttle to go up to 15 knots, after going up the river, it gave two deets on the sensor and wouldn't do more then 1500 revs or about 7 knots. Got back ok and tried it again in neutral (making sure it wasn't a fouled prop) - same thing happened - it wouldn't go above about 1500 revs. It starts OK. Could it be the turbo charger?
