    Fine tuning my carb in acceleration

    can Volvos have manifolds fresh water cooled?

    Just doing some research but I want to do fresh water cooling on my 5.7 GS. I can find lots of fresh water cooling system for my Volvo but they do block only. Does anyone know if Volvo ever did cool their manifolds with fresh water? If so, do you have a Volvo model/year for which I could...

    Is this a lean or rich condition on accel pump?

    Installed new Holley carb (marine 2300) on my 5.7 GS and trying to get all the adjustments correct. Once installed, it would bog down under hard accelerating but would do fine with a slow increase. Replaced the new accel pump nozzle with nozzle from old carb and bog almost disappeared...

    Need details on how to set accel pump lever for 50cc on 2300 Holley

    Have a marine 2300 Holley w/50cc accel pump with the red cam (also have the correct lever for the 50cc pump). Everything I read for marine card adjustment says open throttle wide (WOT) and then check gap between arm and piston so that you don't overextend the pump. Meaning at WOT, the pump...

    I have 99 5.7GL with new long block and new Holley 2300. Trying to set up carb. I have gotten idle mixture, idle speed and timing down and it idles great. Now I am focused on turning after idle. I got a bog off idle. I can go slowly up to speed so I am working on setting power valve and...

    Trying to fix a bog down problem. When I bought the boat from previous owner, had a marine Holley 2300 w/ 50cc accelerator pump. Bought a new marine 2300 from Holley and it came w/30cc accelerator pump.:confused: I have checked the service manual and parts breakdown but they don't say which...

    new motor/carb bogs @ 3k rpm but can push to 4k

    New 2300 Holly carb bogs as I go through 3k but then after a second takes off. At first I thought was fuel shortage but goes to 4 k great after it gets past 3k. Carb was set up using VP service Manuel. It seems like it takes a second to either get vacuum or something. I have new gas, timing...

    is 4k too slow for WOT on new v.p. motor?

    Got a new VP 5.7GS w/new carb. My SS prop will get me to 53mph which great. However, I'm only turning 4100 rpm. Boat is 21 ft open bow at 3100 lbs. I'm pretty happy about the speed but know my top end could be 4800 rpm. Should I be concerned with my prop pitch?

    most 'recent' VP riser gasket instructions

    I want to make sure I use the correct procedure for riser gaskets. My 99 5.0GL uses a 3863191 (metal) riser gasket. Here is where it gets confusing - there are 2 procedures I have found. 1. The instructions say use NO sealants, compounds, or anything else. HOWEVER, 2. VP Service...

    New coupler/flywheel nuts

    I am replacing my volvo engine. Last time I purchased new nuts for the coupler, 6 of them because I read somewhere that they should be replaced everytime they are taken off. The cost doesn't bother me ($40 a set). However, I am seeing it is very hard to find them new, therefore I am wondering...

    New carburetor-ready out of the box?

    I have new GM marine engine and getting new Holley 2300 carb (new carb from factory). The box/seller says the carbs are ready to run. How true is that in anyone's experience? Should I still have the carb tuned once on the motor?

    Need some head bolt questions

    Have a 99 5.0GL. I rebuilt the engine. I am a car guy so when it came to the heads, I was used to torque-ing the bolts. However, Volvo uses torgue with angle. (Please hold the "you should have done it right the first time". I am paying for my mistake). I torgued and then estimated the...
