    1973 Gibson houseboat oil cap

    See post # 5 . If your low on oil you have a leak . And if your real low , air will have entered the system , which means bleeding the air out . They sell a hose ( on- line or maybe on this site , around 30.00 ) that goes on the two relief valves on the steering cylinder , this eliminates about...

    1973 Gibson houseboat oil cap

    Sea Star helm , usually fill hole goes directly into main chamber . I see a mesh reinforced hose , if that hose goes to your fill plug the oil level is good as long as oil is in that hose . Should not use or need oil , unless you have a leak , which will leave a puddle , oil spot under it ...

    1973 Gibson houseboat oil cap

    Edit above post . OP doesn't state how for from the " steering wheel " it is . If it's within a couple inches of the steering wheel shaft then fill it as stated above as it's not some remote fill system. Through me off when he stated it's on the dash , which can be where the gauges are or where...

    1973 Gibson houseboat oil cap

    Probably a Sea Star system, which you can buy there steering oil , 30ish a quart online . Or you can use any light weight oil #5 ( hydraulic oil like they use for snowplows )and under . Transmission oil will also work. Fill to about a 1/2" below the cap , that's for expansion in the hot weather...

    Anodes for Yamaha outboard...Zinc or Aluminum?

    And that has what to do with the OPs question ? Can't wait to read someone's post about how they keep their boat on a trailer and don't have any corrosion issues .

    Anodes for Yamaha outboard...Zinc or Aluminum?

    It's good you put the correct ones on . Maybe if you researched it awhile ago and got the correct material you wouldn't have any pitting .

    Anodes for Yamaha outboard...Zinc or Aluminum?

    Are you slipped at a Marina , on a hook , private dock ? Ask any fellow slippers what they use or have the same results as you ? Stray electrical current will not affect your motor while underway , so that anode is normal to show no wear . I might try to figure out a way to have both types...

    1999 Wellcraft Excalibur

    It's possible it was ordered with a big block. Not that unusual for a 21 + - to have them . In theory the 454 will last longer than a small block. You are working the motor less to achieve the same speed you would with a small block. So if you properly maintain it you should get 5-6k hours out...

    1989 Astro Quick Fire

    A test light is in most boaters tool boxes . Are you getting power to the switch ? Do you have power coming out of the switch or ower at the trim pump . Your switch may be fine , you could have a bad solenoid on the pump a bad connection , worn wire or bad switch . All traceable with a test light .

    Hardtop project

    Shouldn't be , if it is fairly level with the shearline of the hull , as in it's pretty much pointing straight into the wind when going fast . They have them on CCs that run 70 mph all day long among other hull designs Definitely aluminum for roof material , for a thousand reasons. .

    Listing to port side

    Might want to read all the responses before chiming in . Post # 12 gives you the beam along with the HP rating ( although that's not clear if it's for that particular hull or a larger one ) . Bottom and modifications have been discussed as well .

    Listing to port side

    I would try sanding off the lip of the hook so it looks like a continuation of the hulls bottom . Then after putting a tab on the port side , the wider the better , take it out and see how she rides . If still listing a bit , remove the rest of that section. Leaving it on will ,in a small way...

    Listing to port side

    The hull appears to be very narrow , which in itself will list quicker and more severely than a wider hull . The port side of the hull has next to nothing for a planning surface compared to the starboard side . It will allow that side to dig in especially with the larger planning surface on the...

    Gph at various rpm...thoughts?

    Pretty sure you have that backwards . Your 115 is more like a 100hp figuring a 10% loss of hp between the crank and the prop . Try Googling it .

    Stringer question

    Could be . If it was my hull and someone inspected it while second guessing his equipment , I would want a 100% , the stringers are shot from him . Me , I would then look for any clamps ,brackets etc . screwed into the stringers in the bad reading section . If nothing was in the " questionable...

    Conversion from I/O to outboard on Islander.

    When the OP wrote Islander my first thought was a Starcraft Islander , not the glass , Grady White ? . So knee braces ,as noted above , are not used .

    Conversion from I/O to outboard on Islander.

    My thoughts are , replace the wood in the transom, put knee braces in , 45* angle from new wood to stringers . I would find a similar hull with outboard hanging on it and look at the inside transom setup , including width of transom in case they use less width on the I/O setup .

    Need Help & Advice on a Purchase....

    Uhhhh , inboards come with mufflers , inline or cans , my 305s are inline and the 454s are the larger cans . They can " discharge " out the stern , sides or at a 45* angle where the transom and side meet . Bigger engines have bigger exhaust ,they have to breathe , in and out and that usually...

    Need Help & Advice on a Purchase....

    Pretty wild statement. When was a 19' boat brought into this thread ? Might as well said 15 ' . " Big engines are quieter & save gasoline at normal cruise speeds . No they are not quieter , my 454s have a 5 " exhaust outlet , my 305s have a 3" outlet , 454s are louder . Science speaking here...
