I have 1990 454's (Gen IV, I think) I am loosing anti freeze on the starboard engine while at the dock (Not running). I inspect the anti freeze and the tank will be down about 1/8 to 1/4. Refill and check it a couple days later and it's down again. I haven't run the engine. I can't see where the...
Need parts. It is a 1990 4cyl. which I believe is Nissan motor. Former owner did lousy maint. The zinc at the exhaust on the end of the heat exchanger was not changed. Result was that the fitting that connects the hose to the muffler rusted out and fell off. Who makes the generator and where...
I,m getting a knocking noise when in gear on starboard side. Thought it engine at first but when in in neutral no noise I can increase engine speed in neutral and no noise. I looked at the V-drive and transmission and could neither see nor feel any vibration but could feel and hear the noise...
Thanks, Mike. I looked at the stuffing box today. Strange looking packing nut. Its somewhat a trapazoid and 3" across. I have a wrench that opens 3" but the handle is too long. What do you use?
Need to repack stuffing box on 1990 Sundancer 350 with 7,4's and v-drives. Prop shaft miked at 1.25". Sound right? Any tips? This looks like a nasty job. Thanks.
I have a 1990 350 Sundancer with 7.4's and v-drives. I am worried about the packing and looks like 1.25" shafts. What thickness on the flax. It looks really tight under the engines. Any tips? Thanks.
Have bought a 1990 SR 350 Sundancer. I would like to install shoot thru the hull transducer for a depth finder. Was this bottom solid glass or cored? Thanks.
For what it's worth, I found a web site that seems to be useful. It's www.boat-fuel-economy.com. I have flow scans that, when working, confirm that the charts at this site are very close. Like I said, for what it's worth. Also, thanks to nickdj7 and Ididntdoit for the info on GenIV Mercruisers.
We bought a 1990 350 Sundancer last Feb. I found an invoice for replacing the original engines with Gen IV's. Got no engine manuals so I called Mercury to see if they might have one. The lady I talked to had nothing on Gen IV engines. What have I got? They were advertised as 350HP. Thanks.
Anybody buy one of these. I have a 1990 Sundancer 350. Bought the anchor but I see no way to fit it on the pulpit. The curved shank leaves the anchor hanging low and is wobbly. Thanks.
HELP!!! Bought a 1990 350 Sun Dancer a couple of months ago. Twin Gen IV 7.4L Mercruisers and a Quicksilver QS-6.5G generator, 1.2L Nissan type. I did not get an operator manual for either engine. I don't want overhaul these puppies but I do like to do as much maintenance as I can. Need advice...
1990 Sundancer 350 with 454's. Stbd engine won't start. I hear a click when I turn the key. Jumped the starter and starter turned and the engine started. The click comes from one of two electric gizmo's (sorry, I'm a CPA, not a mechanic) that are mounted on the side but toward the front of a...
