Hi guys,<br /><br />I know that if anyone can point me in the direction to go from here it will the the iboats crew !<br /><br />Here's the story :- brand new (to me at any rate) 1996 4Winns 190 fitted with Volvo Penta SX Cobra 5.0 EFi (I beleive this is technically an OMC) with about 200 fresh water hours on the clock. <br /><br />Off we go into a fairly choppy sea after a difficult launch and within 60 yards of the slipway the engine cuts out. 
I start up again and try forwards - nothing doing the engine cuts. Start up again, try reverse, won't go in. So check the prop and find out I have about 6 feet of 1 1/2" nylon rope around the prop !<br /><br />Clear this with a bit of leaning over the side and off we go again - no prop damage - no harm done.<br /><br />Engine runs sweet as a nut now - for about 1/2 hour then just dies. Nothing will get it to go. After an embarassing tow in by the Coastguard, I get the boat home, put the flush muffs on and try to start - still nothing.<br /><br />Here's what I know :<br /><br />1) I found that the pivot housing drain plug was missing ! This could have been removed when the motor was winterised and not replaced or it could have just fallen out. This is the plug on the port side just above where the business end of the ram is.<br /><br />2) There's a great spark - I used a tester.<br /><br />3) There's plenty of fuel in the fuel filter and it doesn't seem to be blocked.<br /><br />4) I can hear what I think is the fuel pump run for a few seconds when the ignition is switched on, then it stops (presumably when it has pressurised the system)<br /><br />5) I took one of the plugs out and it seemed ok, certainly not full of seawater. <br /><br />6) I dipped the dipstick and it looked like just normal clean oil.<br /><br />7) I didn't note the engine temp when this happened, but when I switched on a few mins later the temp gauge showed about 1/3, nothing untowards.<br /><br />8) The engine was run for only a few seconds with the rope round the prop, so I don't suspect lack of cooling from that alone.<br /><br />9) None of the breakers have tripped out.<br /><br />10) Prior to all this, I pulled the water pump and the impeller was OK (ordered a new one anyway) and on the flush muffs the engine ran fine, first turn of the key, with plenty of water pouring out of the exhaust (as it should)<br /><br /><br />Anyone know if all this could have been caused by the pivot housing vent screw being missing ?<br /><br />ps marking on the engine and stern drive say :<br /><br />Engine Type 50FAPHUE OMC Cobra 5.0 Efi<br />S/n T01286579<br />Outdrive Type 2868388<br />S/n T00800403<br />Transom Type 3868175<br />S/n T00359078
