I removed the outdrive on my Bravo 3 Merc on my 310 Sundancer and need some help determining if I need to replace the drive coupler in the engine. My real question is, what is an acceptable wear level on the shaft splines and is it possible to replace the shaft and not the coupler on the engine...

65 watt alternator for Mercruiser 350 MAG MPI This is a low hour (~150 running hrs on boat when removed) used alternator from a '98 model year Mercruiser 350 MAG MPI powered boat. I had it professionally checked/cleaned and then kept it for a spare over the course of seven seasons and two...

Hello and greetings from Osaka. I tried to submit this thread a couple of days ago but it looks like something went wrong as it never appeared. I recently purchased a 1989 Sea Ray Salon Cruiser 31 that has a few problems (it was cheap and I knew the problems ahead of time so no worries!)...

ok – I could use some experienced opinions here… so i took possession of my boat (360) a little over a month ago. on the sea trial everything was fine - we noted a sound around the stbd engine so we did oil samples from the transmission that came back clean. The day I was moving it, the stbd...

I have a 1981 Sea Ray SRV 195 with a 260hp Mercruiser 898 with Alpha One outdrive. This has historically been a great running boat and knew I had carburetor issues. Last fall, and this spring, I had the carb rebuilt and replaced the rotor cap, wires, plugs, air filter, fuel filter and water...

So i bought a boat from a guy online for cheap knowing that it needed some work. What i didn't know was how much work it was really going to need. So long story short the mercruiser 260 that came with the boat was beyond repair. I found a volvo penta 260a from around the same time period. So im...

Of course I am talking abot the avaialble space in a 1994 SeaRay 185 engine comparment for changing the plugs on the port side :) I just bought this beautiful boat from a neighbor who was the original owner. Its a 94 185 Five series and there doesnt seem to be much info on that particular model...

Wanted to know if there is a thread about replacing a starter on my boat, it has a Mercruiser 5.0 EFI. I have changed one before on a I/O about 8 yrs ago and, I have the correct starter, just wanted some pictures or advise to make it go easy as possible.

This past weekend I hit something out in the bay and damaged my lower unit. I was able to make it back into the marina. The boat seems to drive fine but is not holding oil due to a crack in the lower unit. See pictures attached. Any help with repair recommendations would be greatly appreciated...

This is my first post on here and everyone seems helpful. I hope someone has a good diagram of the wiring on the 5.7 mercruiser inboard I am really just trying to get running after an engine swap. Its in a 1985 21' with an OMC Outdrive. Starter turns it but I cant seem to get it to fire...

I rec'vd two Merc elbows that shipped with gaskets for twin 4.3/LX engines. The gaskets had two slots that were cut out right where the coolant (closed system) is chambered. I attached the elbows and when filling with new coolant, I realized that I had more than 7 gallons added to a six cylinder...

I need serious help, from somebody who knows Merc 260/5.7 carb engines inside and out, or at least has knowledge and experience working with them. Knowledge of these as twins, in the Amberjack configuration would be even better. I've got a 87 270 Sportfish (Amberjack flybridge) with twin...

I have a new 2010 Sea Ray 205 Sport with a MerCruiser 4.3L V6 MPI engine. I just received a recall notice from Mercury (MerCruiser Service Bulletin 2010-12). The power steering fluid cooler needs to be replaced (the current housing is polymer and can break). I did some searching to find out...

Hey all, I am the proud new owner of a 1974 SRV240. I recently hooked it up to water and ran it to see what i was working with. It sounded good, got water coming out of the prop, then all of a sudden water came gushing out of the trans fill dipstick, did some research found out it could...

Hi, I have just purchased a 1999 Sundance 340 with twin 7.4 litre MPI Mercruisers and V-Drives. The boat is in amazing condition and I am ecstatic with it in all except one way. The enginrs run beautifully, oil pressure, temp everything; however after about 15 - 20 minutes running the port...

Hello everyone, I am new to your site, but i am glad to find other boaters with old but classic, fun fiberglass boats, I bought this boat 5 years ago, it is a 1976 240 SRV, and it was a mess when i bought it, it took a lot of tender rubbing and knuckle busting to make it run, and on its final...

Having some trouble with one of my original engines - a 350 chevy 255hp mercruiser (1978). Looking for a manual on it if anyone has one. Any help is appreciated, thanks!!

Hi Gang - About a year ago I had the bellows and shift cable replaced on my Alpha One outdrive. The shift into forward now takes a longer travel to engage, and it slowly seems to be getting worse. The original mechanic is several hundred miles away, so I'd like to know if someone can recommend...

Hi! Changed the trim sender kit last year. After this the trim meter on the dash board moves just a tiny bit until it swings full up. the trim limit is working fine , and so is the trailer switch part as well. From what i found the resistance in the sender is 0-240 ohms. but running the meter...
