went out on my pontoon today and the eng ran great for 45 min. then it slowed as I was heading to ramp. I did not see water coming out the pee hole when this happened. Should I pull the water pump and inspect? The pee hole is clear. the mercury is a 40 HP 4 cyl. I think 1991. ser is OD054364. thanks for any help/ I do have a Seloc book

yes it was. I pulled lower unit and impeller was cracked and loose in pump housing. I replaced impeller, replaced plugs, changed oil in lower unit. Fired it up on muffs and I have a better stream than I have ever had.. Only second time I have had it in the water was when it quit pumping. compression 130 on 3 and 120 on 4th.. Now back to the lake.
