    2002 Mercury 25 won't start

    I picked up an 11' Boston Whaler this past summer that had a 2002 Mercury 25hp 2 stroke with remote start/throttle. All was fine early on. Then, without warning, suddenly the key start did not work. Not even turning over, zero, nada. Nothing trying to happen with key on. If I turn the key to...

    Tamd40b

    We are looking at a trawler with a pair of the listed Volvos. They have 4300 hours and look well cared for. I am told the freshwater cooling system was just upgraded. I haven't seen or heard them run. My internet research looks like these engines are expensive to maintain due to parts...

    555 questions

    We're looking at a boat with 555s that have 3700 hours. The engines appear to be well kept by the seller. What is the typical life span of the 555 and what are the pros/cons of the 555? Can they operate at trawler speeds 75-90% of the time with the occasional hard run to blow and clean things...

    6-71 T question

    We´re interested in a boat with 6-71 T1 (435 hp at 2600) engines that have 2000 hours. In doing a general search, I´m not reading too many favorable things on them. In fact some people tell others to "run from them." I'm looking for more knowledgable info before I spend a lot of money on a...

    440 antifreeze loss

    Another coolant loss question.... I've read a few past posts, here and on other forums regarding coolant loss, but I thought I could narrow my symptoms with the Chrysler experts here. 440 full FWC-I am monitoring coolant loss from the resevoir after running. I marked a line on the external...

    440/AFB backfire

    I have twin 440s in my boat with AFBs. I pulled one of the carbs because of a fuel leak. Turns out, floats were set too high. Guy who fixed it, solved the problem, but also moved my mixture screws from where I had them. Now, when I cold start, I am getting backfiring until she catches and...

    Carter AFB

    I have twin Chrysler 440s in my boat with Carter AFBs. I wanted to run my carb problem by an expert before I tear into my problem carb. One of my carbs was rebuilt this past spring. Since that time, whenever I shut down the engines, the rebuilt carb seems to absorb the heat from the engine...

    440 starting issue

    Another problem with my 440s....For no apparent reason or oncoming symptoms, my port engine would not even turn over. Once the key was turned, it was if I was trying to start it when in gear. As you know, you will not get a response. I opened up the electronic ignition plastic cover, nothing...

    Exhaust collecting tube

    On one of my 440s, I developed a hole on one of the tubes for the 'Y' or exhaust collecting tubes-post risers. It transports the exhaust and cooling water to muffler and overboard. Anyone know of a distributor or better material to use to future problems? FWC, I boat in salt water. Thanks

    Warm elbows-440

    This winter, I replaced risers, spacers and swivel elbows on my FWC 440s. My first engine was stbd and sea-trialed it, seemed fine. I shot with IR gun all around and temps were good. Top of swivels were 80 degrees and cool. Good water flow out transom. Next did port engine and same thing. No...

    Spark plug wires

    Any recommendations for plug wires? I have twin 440s on my boat and doing spring tune up to include wires. I have electronic ignition. 8 or 9mm? I'm looking at prices online and it seems prices are all over the place. I don't mind paying some if the person over the counter is telling me the...

    440 Thermostat

    Chrysler 440 FWC, runs between 165-170. I'm updating risers, etc. for preventive maintenance. I am always trying to improve performance and/or helping the ol' girl out. While my antifreeze is drained out, I thought about swapping out thermostat. I have seen 'high flow' or performance...

    Fwc 440

    I'm redoing my FWC exhaust on my 440s and want to do it right the first time. In reading through past posts, I want to make sure I understand the burping concept. Once everything is reattached and I've refilled the system with antifreeze, I run the engine with expansion tank cap off. Engine...

    440 Thermostat

    I am looking for a part # for a 440 FWC thermostat. I think I saw one for $120 but only $13 for a small block. I put the last thermostat in that I bought from Napa but after doing some reading, is it doing the correct job? I'm doing my cooling system and while everything is apart, I want to do...

    Riser surfaces

    I'm replacing the risers/elbows/extensions on my FWC 440s. The parts came painted to include the mating surfaces. Does the paint need to be removed from the mating surface? Thanks

    Dieseling 440

    Back from vacation and both my 440s (with Carter AFBs) ran great. At 1860 RPM consistently (8.5 kts) I averaged 6.7 gal/hr total. My question is, after a day's run coming into a harbor, my stbd engine would begin stumbling as if wanting to die. If I gave it a little higher throttle to keep it...

    8hp Impeller

    How hard is it to change out a mid 80's, 8hp impeller? I don't have the ser# on the shaft as the previous owner(s) did a modification of some sort. Is the lower unit dropped and then.... what? Thank you.

    8 hp impeller

    I recently purchased an 8 hp Johnson which ran great/good peeing, when the previous owner ran it for me. We believe it is an '86. However the id plate is gone so I am unsure on the year. My question is; I want to establish a base line so I know what's been done and what needs to be done to...
