Flagship marine engines did the rebuild, Asking around I understand to be a very reputable marine engine builder. they tell me the exact same cam spec was used. (New though). Could they be full of it, maybe I just have to trust them. Same mefi 3 that was on the boat before. Same intake, Although I did get it machined to be perfectly flat. When I took the manifold off i did check the valve lash to see if maybe they were to tight. Flagship had them all right on the money. Half a turn passed zero lash. Same TBI, and distributor. Although all new Volvo Penta ignition module, pickup coil, Plug wires, tps, iac, coolant temp sensors, MAP sensor, on my second set of spark plugs.
I have the Mefi scan software from OBD and coolant temp is at 72.5 C (162.5 F). Bob looked at a scan i sent him but didn't know if the injector pulse width was correct or not. I don't have the fuel tables or the knowledge to understand the numbers either. Bob is great don't get me wrong. I'm just not super happy with were it lead me.
Yes OBD said it was mefi was good but now, in conversations with him, it was a basic test and he says I should try replacing it. mefi 3 units don't grow on trees and the programming would have to be changed for my engine. So "trying" a replacement doesn't feel like a solution to me. I thought John seemed like a good option but, I don't know now. Lucky for me most of the new Volvo Penta Ignition parts I didn't have to pay for. The Marina that had my boat for 2 months didn't charge me when they gave up on it.
I am sure you can sense the frustration. Certainly not intended for this group you folks have been fantastic!
I now find myself waiting at least two weeks to get the mefi back from John but PLEASE keep the ideas coming. I need to get back on the water relaxing instead of stressing. LOL
