New issue with power trim. The boat has twin Mercruiser Alpha outdrives. I recently had a problem with an oil leak. We fixed that. However, now the outdrive will not trim down with the switch after it's been trimmed up more than 50%. I can trim up with the switch from any position. I can trim...

Thought that I should finally post resolution. The oil leak was cause by a corroded manifold, not bad hoses. The block corroded at the hose threads, so the hose popped out under pressure. The repair process is just as Chris Dauth described. It took me a lot more than an hour but I'm not...

Awesome directions. I had some small hope that I could do this in the water. Guess not. Thanks very much!

I think I need to change the interior hoses for my stbd power trim hydraulics. I can't see where and how it connects to the manifold. Does anyone have a diagrams or pictures so that I can see what I'm looking for. What parts to I need to remove in order to get to it? My story: I have a '98...

I am looking for tachometers and a sync meter for a '98 290 DA with 2x 5.7 EFI Mercs. Any leads would be appreciated.

On further inspection, I found that the connection to the positive side of the alternator was completely loose. It looks like there may have been some arching at some point. I cleaned up and tightened both terminals. The boat started fine, the voltmeter needle was steady, but low 10v. No alarm...

Thanks for the feedback. The batteries are OK, so far. I'm pretty sure they are doing OK because I've had no problem starting both engines repeatedly. I will check voltage with a voltmeter across the alternators and across the guages. Someone on another board also suggested that I clean the...

I appreciate any advice on how to diagnose and fix this issue. My boat is a '98 Sea Ray 290 Sundancer with twin 5.7 EFIs with about 600 hours. This issue popped up during the return leg of a quick trip to a dock & dine. After cruising for about 15 minutes, the alarm on the port engine...

I'm getting a pretty loud noise from the stbd outdrive. It's louder than a ticking, but not as loud as a banging noise. I didn't perceive any vibration. I hear it about equally loud standing on the swim platfors as I do with the engine hatch open. I can hear it and feel it when I turn the prop...
