Hello all and hope your day is well, I have set the max advance on my 85 150 and I'm woundering if there is any issues with how I did it? Due to not being at wot rpm, I set the advance with boat in the water under way however, I advance the throttle until it touch the max advance stop, check and then adjusted and repeated, I did not feel comfortable trying it at max rpm as this is bass boat and I cant bring my self to stand over the engine with the light well doing 50+ mph.
