    Volvo Penta GXi-E Low Power and 2 DTCs

    Finally got boat working well! Replaced cap and rotor AGAIN and now jumps up to plane with 10 people in the boat (and at altitude too, btw). This was the first thing I replaced (with OEM) when problems started a little over a year ago. Must've had multiple issues when I first replaced, but...

    Yep, I live in Colorado. This was recorded at Horsetooth Reservoir at 5,430'

    I didn't make any recordings with engine off. I will have to check when get up to the boat again. I was curious what the pressure readings of the manifold should be at WOT because my recording is showing readings close to atmospheric. Wondering if there supposed to be high vacuum at WOT

    You are probably right as the flapper parts are not listed in the exhaust diagram for the gxi-e.

    Ah, you are talking about the intake. Yes, I have cleaned the intake spark arrestor (multiple times), but you do have me looking into the exhaust now. I am going to see if the flapper (which apparently isn't needed) might be causing the problem.

    I haven’t looked at the exhaust at all but good idea. I will check it out, thanks!

    Hey QBhoy, I did try moving the distributor 1/8-1/4" clockwise and counter clockwise which did not seem to make things better, in fact they seemed a little worse, but hard to say exactly. I did record scan tool readings for both directions which I can send if you think it would be helpful.

    Hey tpenfield et al! So after a long winter I finally got the boat back in the water. I went through the diagnostic procedure for clearing the DTC 41 codes with a test lamp this time and sure enough what was reading 12 volts with DMM did not light the test lamp which lead to "replace ICM"...

    Perfect thank you! Apparently I'm unable to call it correctly. I will refer to it as the flux capacitor from now on.

    Thank you tail gunner and alldodge. I am learning a lot reading your responses. Got any tips on how to properly phase HSV (which I will stop calling a distributor, lol)?

    Thanks Brich. From what I remember, the pressure was 55-60 at idle and never dropped below 45 at WOT under load. What I can't remember is if stabilized higher. Another thing to test again when I can put the boat in the water.

    Good to know wrench, thank you! I have purchased a test lamp and will go through the service manual steps again using a test lamp when I de-winterize.

    I have use two different pressure gauges. I measured the pressure at idle and watched the pressure while under load at WOT and pressure never dropped too low (never went below 45 psi if I can recall)

    Good to know alldodge! What I meant was at or below but within 10% of full mark on dipstick. I have never measured it over full mark.

    Thanks for the reply tpenfield! Yes, it does have variable timing. I don't know enough about the timing to know what are good or bad readings. The history: I just bought this boat last summer. It did seem to run properly for the first 3-4 outings before the power issues started. Before I...
