    1995 Volvo 7.4 - 2 Oil Questions

    Re: 1995 Volvo 7.4 - 2 Oil Questions The dipstick tube is hooked to the bottom of the pan, so you will get all the oil out when you suck it out of the dipstick tube. Yes, it holds 9 quarts if it's fuel injected engine, according to the Volvo service manual for the HU models, but you haven't...

    omc 5.0 gm with thunderbolt lV

    Re: omc 5.0 gm with thunderbolt lV No, the method from that other forum is for the Delco EST ignition, not the Thunderbolt IV. If you want to get rid of the OMC ESA system completely, then you would wire it like a Mercruiser (see diag below) I would eliminate the ESA and the overstroke switch...

    Mercruiser: possible timing issue...Help

    Re: Mercruiser: possible timing issue...Help You need the serial number of your engine to be sure it's not a 96, not uncommon for boats to have a year older or even year newer engine than the year of the boat. The model year changes at different times. Assuming you have a 96 or 97, you would...

    Calling All Ontario Members

    Re: Calling All Ontario Members Just so you know, the link you posted is not a dropbox file. It is a .pdf file using the iboats forum software. Seems you have split the Excel file up into 4 pages and really lowered the file size. But it looks great. It's obviously now a vector file and not a...

    6.2 running hot above 1500 rpm.

    Re: 6.2 running hot above 1500 rpm. You won't see a problem, but that doesn't mean there isn't one. Plumb in a piece of clear hose on the raw water pumps inlet fitting and go for a run and see if you see air bubbles in the inlet stream, if you do, you have a leak that is allowing air into...

    Usernames....... the weird ones

    Ok, I can get a handle on most usernames where they have your name in them, type of boat, a bit of a saying, etc. But some usernames just don't seem to have any rhyme or reason behind the jumble of letters and numbers. For example (Not making fun of your name, just showed up at the right/wrong...

    5.0 GXi thermostat...

    Re: 5.0 GXi thermostat... You have a thermostat and rubber ring for a (F) model. You do not have and F model, therefore the thermostat you bought for the F model is the wrong one. Again, I don't have a clue what number you seen in your last lookup, but the stats for the Closed cooled and the...

    another spitfire conversion

    Re: another spitfire conversion Been wanting to do this for a while on that conversion, so found an OEM color wiring diagram with the Spitfire system and changed the drawing. It's a lot easier to read that the big block diagram. Started with this. Then removed the old and added the new...

    5.0 GXi thermostat...

    Re: 5.0 GXi thermostat... Your picture worked fine. The way it is in the picture is correct, the thermostat does not go in the manifold. Are you sure you have an F on your model number? That would indicate you have closed cooling, and from the looks of your thermostat and housing, you don't...

    '89 Bayliner OMC Cobra Distributor

    Re: '89 Bayliner OMC Cobra Distributor I don't see any problems installing an EST distributor kit on your engine. I don't see the ESA module, but that is easily worked around by some simple rewiring and setting up your shift interrupt switch like a Mercruiser. It's been done before with no...
