    2000 Mercruiser 5.0 Thunderbolt 5 Ignition idle issue.

    Well, we have been using the boat and it is going great guns after the advised adjustments here! While all is now good engine wise on all levels re cold starting, power transition and delivery, idle and consistency, it does seem to be going through a fair bit of fuel. Quite a bit more than my...

    2000 Mercruiser 5.0 Thunderbolt 5 Ignition idle issue.

    Is that idle 650rpm while in gear neutral or out of gear neutral please?

    2000 Mercruiser 5.0 Thunderbolt 5 Ignition idle issue.

    Thanks heaps again alldodge. I also think my idle speed is a little too high as shifting into gear from neutral (directly and quickly) brings a substantial and concerning crunch. I think it's at around 800rpm. Needs to be closer to 650-700rpm? Would the 100 odd rpm be the reason for the excess...

    2000 Mercruiser 5.0 Thunderbolt 5 Ignition idle issue.

    So as a final question and to confirm, I should be adjusting for more choke and turning the choke adjustment clockwise (according to the above diagram from alldodge)? Also there seems a very limited range adjusting in this direction...

    2000 Sea Ray 190 CC Hull Soft Spot

    Well, the repair is now done (I also contacted a local fibreglass expert for any additional last minute advise before I sorted it). I believe the job is done properly and the result is really strong with the hull being solid as a rock. A little luck also went a long way to actually allow a DIY...

    Apologies. All my comments relate to the storage area only. So when I say flooring, I mean flooring of the storage locker...

    2000 Sea Ray 190 CC Hull Soft Spot

    Thanks tpenfield. Took your advise, removed the cushions, stripped the carpet from the below storage compartment and... It seems to my untrained eye that I might have had a bit of luck. The damaged area is directly in-between the bulkheads of the accessible storage area. All fibreglass and the...

    2000 Sea Ray 190 CC Hull Soft Spot

    Apologies but my pics are not brilliant and are not as clear as they might be. There is no discolouration in pic 3, just shadow. The pic is only meant to show minor spider / stress cracking. I don't suppose there is an easy way to determine an "an impact from flotsam or stress cracking from...

    2000 Sea Ray 190 CC Hull Soft Spot

    Yet again thanks guys. Post pictures and videos! We can't analyze anything with just text. Fair point and well structured. Please see below. The damage with my thumb for scale is in the middle of the affected area. The larger stress/spider cracking is about 10" forward of the damage (looks...

    2000 Sea Ray 190 CC Hull Soft Spot

    Hi all and thanks for the advise / information. So the tapping of the hammer on the hull does not provide a super conflicting sound though there is a minor / medium difference in the affected area. Again, yes there is a difference, but it is not solid, solid, solid, hollow if you know what I...

    2000 Sea Ray 190 CC Hull Soft Spot

    I have a 2000 Sea Ray 190 CC. Everything was proceeding perfectly regarding getting the boat to as new condition until I took the boat for a major service on the engine and outdrive to ensure I was on the best start possible mechanically. While this all came up great, the marine boy's advised...

    2000 Mercruiser 5.0 Thunderbolt 5 Ignition idle issue.

    I guess the obvious question is if I adjust the choke to allow more fuel in the cold, will this new setting be detrimental when the temp is warm or hot?

    2000 Mercruiser 5.0 Thunderbolt 5 Ignition idle issue.

    Wow, thanks so much for the advise and how to diagram. I will give it a go. We are into spring here so probably will struggle to get the lower temps to test though...

    2000 Mercruiser 5.0 Thunderbolt 5 Ignition idle issue.

    Hi and thanks for the reply. I didn't add the temperature in the first post as I assumed Mercruiser engines were designed to run efficiently regardless of it being hot or cold. I guess never assume. Apologies. Restarting the engine was not an problem as long as some throttle was applied...

    2000 Mercruiser 5.0 Thunderbolt 5 Ignition idle issue.

    Well here's the thing. When I had the idle issue it was cold. About 0 degrees celsius. Ran the boat again today and it was much warmer at 12 degrees celsius with no issue at all with idle. Is that standard with the setup I have that it doesn't like cold weather?

    2000 Mercruiser 5.0 Thunderbolt 5 Ignition idle issue.

    G'Day all, I have a 2000 Sea Ray 190 CC with a Mercruiser 5.0 Thunderbolt 5 ignition. I am having idle issues where the engine idles okay for approximately 1-2 minutes then slowly reduces rpm till it stalls. I have adjusted the idle rpm adjustment screw with no joy. Any idea's? Thanks heap...
