    Temperature Gauge not working - Volvo Penta 5.7 GI-E

    I have a 99 5.7 GSI and I am having the same issue temp gage is pegged at key on/power. I also Have tried everything that I could think of, new gage, new temp switch checked wiring with no changes. this could be the issue. I "found" a two wire connector behind the #1 fuel pump and filter...

    1999 Volvo penta 5.7 GSI stuttering/cutting out - temp gage

    I have two wires to my T stat housing they are black, and white/blue. I cannot find a tan wire anywhere, the only tan one goes to the back of the alternator. I have swapped the temp sensor and the gage both with new, the wires on the back of the gage is tan though. I also have a single wire...

    1999 Volvo penta 5.7 GSI stuttering/cutting out - temp gage

    I have two issues that I need help with. 1. A few trips ago after sitting on the lake for an hour or so I started the engine (easily) and throttled up. I get about 5 seconds into taking off and the the engine surges badly almost dying, then taking of again and again. Like the choke is on and...

    Volvo Penta GM 5.7 TBI low power at take-off

    in an automobile when you detonate there is a very pronounce "pinging" wont the boat do the same thing? I have listened closely for it. I understand what your saying, I do, and I know i am..randomish in my timing placement however you can estimate fairly closely, also I can measure the...

    Volvo Penta GM 5.7 TBI low power at take-off

    Wow, I advanced the timing on the boat to I don’t know how far 8-12 degrees there are no marks on the block or the vibration damper. But damn what a difference! Comes out of the hole pretty damn good for a 4400 lb boat and the top speed is around 40-44 which is too fast for the choppy lakes...

    Volvo Penta GM 5.7 TBI low power at take-off

    I will keep that in the memory banks but I think that is more than I am willing to do, it seems stuff is always more complicated or causes other issues LOL. I will try the 8 degrees BTDC timing do you agree with that?

    Volvo Penta GM 5.7 TBI low power at take-off

    got it! move the 4th mark on the right to the V notch! I thought that but after talking advance and retard timing CW CCW front back I get mixed up! thank you for straightening me out. I have read a few posts stating that slightly retarding the timing increases low end torque while...

    Volvo Penta GM 5.7 TBI low power at take-off

    Just to make sure I understand I am looking at the rear of the motor, I want to move the 4th mark to the right of the large line to the v, in base timing mode. Why is it so different from truck timing?

    Volvo Penta GM 5.7 TBI low power at take-off

    For the timing… I get confused, there is a stationary “v” on the engine, and the engine rotates CCW (damn I think) so I move the distributor so the vibration damper mark moves 8 degrees to the right of the v notch 8 degrees, I think there are 2 degree marks on the vibration damper. Is that...

    Volvo Penta GM 5.7 TBI low power at take-off

    I don’t feel I need a huge gain just a bit for tubes and wakeboards so they can pop up, and not drag along, I don’t use top speed at all. I don’t know they are F5 front and rear and I don’t know anything about duo props or Volvo stuff

    Volvo Penta GM 5.7 TBI low power at take-off

    Agree I just need to optimize what is available and if there is a simple torque /hp increase, do that. Do they have a performance chips for boats? I know I can change props but duo props are a spendy last resort
