SMX Impeller failure
This topic has 7 replies, has 6 voices, and was last updated by 10 months ago
June 14, 2023 at 1:16 am Do these things randomly fail or does there have to be a reason? Exactly 5yrs since I put it in new. The last time it failed 5 yrs ago some ding bat left the sea cock closed, thats not wat happened this time PS when I install the new one rotate it CW or ACW? Mark

Turbo slow to spool up
This topic has 10 replies, has 3 voices, and was last updated by 1 year ago
March 18, 2022 at 2:45 am This started happening after a long period of slow running (trolling Lures), now happens more often. From slow running, push throttle up nothing happens. leave it half way and rpms slowly rise, then it springs into life turbo winds up and we are up on the plane 2500 rpm.. Intercooler is clean, AF is clean, hull is clean, prop is clean, boat is not over weight.

October 5, 2021 at 4:08 pm It started to get a bit sticky couple of years ago, hangs on for a second or so but recently started getting worse, last start it stayed engaged to flywheel for about 3 seconds after starting. sorry dont have a good photo of starter and attached photos the aftercooler is removed for servicing. Any advice before i start pulling things apart? Thanks in advance Mark
4 RepliesJanuary 24, 2022 at 12:48 pm Congrats on fixing it! I had a problem with my starter recently, sometimes I pushed the start button and it would not do anything but you would notice that smoke was comming from the starter cable so and starter was not doing anything. I changed the mag switch, cleaned everything and still did it one more time. I got scared of the situation and decided to just get new batteries and a brand new Delco 38mt starter to replace the old 42mt. My guess…

June 1, 2018 at 11:58 pm Hi all. So whats the damage if this occurs?
4 RepliesJune 4, 2018 at 9:20 am thanks for taking time to respond Larry. So thats what can happen, thats scarey..

I pulled the aftercooler a …
