    454 distributer/timing problems

    well I think Ive figured it out, when I pulled the module off of the riser to find a part# (not legible) I saw that the resin filled backing had a hole in it, not sure from what. now the challenge of finding a new one, mercruiser has a kit to upgrade the module to basically a T5 (part #15248T02)...

    454 distributer/timing problems

    Hello, my port side 454 has been running like crap for a bit and I've chased it down to the distributer (Tbolt V large module 1984) when I put a timing light on it its all over the place, this results in a jumpy idle and an occasional backfire at speed. is this likely the module itself or the...

    Tr installation/ gimbal bearing problem

    I just changed the gimbal bearing and now I can't get the drive all the way in, it's about 1.25" out, the new bearing went on the input shaft all the way into the orings but tended to bind up a little on the shaft, I used Emory cloth to smoothe the tapered area of the shaft where it was binding...

    Tr questions

    What is the difference between the 1973-76 tr drive and the 77-93, and is there any compatibility? A guy has what he says is a 1976 for sale, the only difference I see Frome what I have (1983) is he has the merctrans and I have the velvet drive, witch is fine I just want a spare drive and gimbal...

    Mercruiser TR drive questions

    I just picked up a 1983 Searay Amberjack 255 with a 454 and a TR drive. The only bad thing I can find about these is the rarity of parts, that being said I'm on a mission to get some spare parts. I've found a used lower unit but its a left hand rotation and mine is a right, now because the...

    Mercruiser inboard exhaust question

    I'm replacing the risers and reducers on my new boat (26 tollycraft w/90's 255 mercruiser inboard) the risers were in bad shape, I dont think they would have lasted the season. My question is this: can I use fiberglass reducers right off the back of the risers? the mercruiser reducers are...

    Inboard prop question

    I recently bought a '26 Tollycraft sedan, its heavy (9000+) not really a planing hull but they will if you want to burn the gas, the older ones like mine came with a conventional drive that left limited room for a prop of adequate size, I posted on the tolly forum about trying a 4 or 5 blade and...

    Questions about an older Chris craft

    Getting real serious about a 1969 31' CC commander, twin 327q's low hours since rebuilds, my question is why did CC install these motors backwards? and not its not a V drive boat, the front of the crank mates to the trans its hard to see exactly how this works because of the heat exchanger is...

    Hotter thermostat?

    Right now I have the stock (145*) tstat but am thinking of going to a 160* or a 180* the only reason for this is to get some better heat out of the heater, I assume the only reason for a 145* tstat is to keep detonation under control. My boat is a little under propped and I've never had an issue...

    Hard starting-still

    In the last few weeks I have installed a new carb, changed the plugs and checked the timing. It runs well and the fuel economy is up a little bit, but still even with a choke that works it takes 15 sec. or so of cranking to start cold and 4-5 sec. when its warm. I was hoping in addition to other...

    First impressions of my new edelbrock 1409

    First, I already had an edelbrock 2104 manifold with my Q-jet on top, so that was already done. My problems with the Qjet- no choke, sometimes it could be hard to start. The fastest I could go without getting into the secondaries was 3500 rpm after that fuel economy went from the low 2s (mpg) to...
