Hi, I have a 1989 454 Mercruiser Stern drive w Bravo 1. Today I fired it up first time since layaway, where I properly winterized w RV antifreeze. Motor jumped to life as usual, and on water muffs, seems like I couldn't discern the pink antifreeze coming out of exhaust. Then around when up to...
I cut out a few areas of rotten deck in my 1989 Maxum and am replacing with 1/2" exterior grade plywood, wetted out with epoxy. The rest of the deck is fairly solid, but the top layer (under the carpet I am going to reuse) of what looks like chop strand resin is heavily abrated and UV weathered...
I am planning to convert my Thunderbolt IV ignition back to the factory setup with riser-mounted module, coil and distr. The previous owner installed and ran an auto HEI distributor with the coil set on top of the dist. cap. Not realizing, i ran the boat for 2 months last summer (454 BBC) and...
I have read other posts and get it all except getting the power to start the motor. I have an 1989 454 and would love an idiot proof sequence of starting it out of the boat. I know how to get water and gas to it. I have what I guess is a 10 point harness at the motor. The distributor may...
I have searched forever and find info. on every other type of conversion. I am looking to put a 1989 454 carb Bravo 1 (from a Maxum 2300 sc) into a 1998 Maxum 2300 SC which currently has a seized 305 or 350 with Alpha 2 drive. What issues would I have to address? Particularly, will the...
79 Merc 228hp, newer shift cable, just put on a used outdrive, had the shift professionally adjusted and it shifted well (i.e., normal) for the first many outings. In the mean time, I have noticed very almost microscopic metal flakes the continue to collect on the magnetic drain plug...
Hi,
Folks on this forum are very helpful! I have a mid 70's 55hp Chrysler which is running well except for what appears to be a fuel leak just below the cylinder drain cover. I have read posts indicating that older engines did not recirculate and dispelled excess fuel, but this is a good...
Motor #1 - title says 1975 but plate w/ model # seems to be missing. Runs well after shop tune-up, but prop shaft leaks lube and need to reseal LU.
1. LU came off easy, but can you confirm part numbers for 1. impeller/kit and 2. lower unit seal kit (MarineEngine.com and Iboats seem to miss...
I have a 79 I/O pre-alpha that has a newer lower unit. At the end of the season, I could hear a vibration sound that seemed to be from the bottom of the 5.0 engine that would disappear after warming up for 5 minutes. My mechanic says he traced the vibration to the upper case of the outdrive...
