pushing engine that certainly would be true, to some extent. i did not push any engine. i assume that my bad tac was relatiely useful so one engine or two i used the same rpm. for that rpm, one engine got about 7 mph, with 2 engines it got about 8.3 mph, not 4.15 mph.

trying to wrap up all this has been very helpful. it is clear that in general the multiviscosity characteristics of oil are not understood by every user. half of my initial proposition was in response to past queries where a two engine captn wondered how it would be to run just one. I tired...

that graphic is most informative. thank you for attending to this so well. I would not presume to be so offensive as to waste anyone's time and good will on this. One tac is defunct, the other says I have been running at 3400 rpm. Is it correct to infer from that graph that the engine will...

this has all been most helpful. thanks to every one of you.

very helpful, thank you. the 15w turns into a 40 when it warms, which is when the engine gets warmed up. i not think most people on earth know this.

engines start after about 3 revolutions, when cold. mild white smoke exhaust for several minutes when started cold, clearing up after 5 min. After 1200 miles,mild thin blackening on transom. oil not in bilge. I am stuck with this situation, I and boat too old to mess with rebuilding engines...

Previous owners used 10w 30. Your response is quite helpful. I am going to switch to 50w.

perkins about 90 hp. could be the tac is off. most instruments on this boat are off or out. i put some massey ferguson stuff in it trying get some useful info.

they are worn out, long abused by previous owners. i am 81 and worn out sort of too, so we will just keep on keeping on.

Gulfstar 36, 2 perkins engines, going from New Orleans to Brunswick, 1200 mi, 19 days, 1973 boat, engines burning, each 1.5 qts of 10 w oil per hour, at onset, threatened to scuttle the trip, not enough oil avail for this. started running only one engine and swithing every few hours. running...

there are various crimpers used for alum and copper ferrules for art work and fishing. the area of home depot and lowes with the terminals will have a variety of long handled heavy head and handle crimpers,as will a fishing supply store. depending on the metal alloy on the terminals, they may...

insurance, anchoring. check with other insurance companies. i have progressive on a 1975 trawler and its not nearly what yu are paying. I have had one boat lost to Katrina;, and another Westsail 32 put on land in a hurricane .Progressive did not quibble in any way over covering the losses...

cant sit on the seat if sailing, i mean. rowing and motoring is much better.

carrying capacity i weigh about 230 lbs. all muscle as you might expect. have tried these 8 foot sailing, rowing whatever and find that any movement causes lurches. in the boat alone,i have to get in the center. a bit off center and the other side skyrockets. the centerboard or dagger is...

thanks for all the suggestions. i did the voltmeter suggestion as a conduit between alt and batt and got next to nothing, so alternator bad despite being just rebuilt. wiring maze led me to a wrong connection that cooked it apparently. alternator now in shop, shop in limbo, we in limbo...

very helpful. Thank you.this is a two battery to two alternator system that is isolated from each other. I didn't want to connect two batteries so if one of them went bad it would not drag the other one down. However your comment about the one wire alternator seems pertinent here. This...

that is very helpful. thank you.i am seeing my way out of this situation now.

thank you. all in your first paragraph is how it is now wired to battery switch. i hve 2 batteries, separated at switch. the ammeter issue is something i was wondering about. if the meter is not working does that prevent the charge from going from the alternator to the battery? i am going...

I have a gulfstar 36 1973 trawler. NEW alternators on both perkins diesel 90 hp engines. some instruments do not work. amp meter on stb engine shows amp delivered. amp meter on port engine shows nothing. I assume the alternator is working, but dont know if the amp meter is bad or the wiring...

alternator wired directly to battry 1973 perkins 90 hp diesel, either alternator not putting out or wiring bad. old boat, old wiring, lots of wires not connected. leery of reconnecting as i burned up some wires connecting what appeared to be obvious disconnects, but that did not work out...

i have a 1973 gulfstar with 2 perkins 90 hp diesels. one alternator either bad or wiring bad. can i wire the alternator directly to the battery?

Thank you Dave. i thought a reply would take a week at least. The instant help makes me glad my wife insisted that i put this question out there. I am going to try to find the very small but strong technician. As it was i was just going to abandon the generator.

I have a Kohler gen. exhaust leaks. it is under the side deck, with about 3 inch clearance on top, cannot see the exhaust side even with a mirror. might be the mixing elbow or gaskets or something else. It seems impossible to get at that side of the engine to fix anything. No normally sized...
